The boys were playing cricket.
Explanation
The active sentence is in the Past Continuous tense. In passive voice, it becomes: 'Cricket was being played by the boys' (Object + was/were + being + V3 + by + Subject).
چونکہ جملہ Past Continuous میں ہے، اس کا Passive بنانے کے لیے 'was being + third form' لگے گا۔ جملہ ہوگا: 'Cricket was being played...'

49📚📝 EnglishConditionals
Choose the correct option to fill in the blank:

If I had left early like everyone else did, I ___ sitting here now listening to all this rubbish.
Explanation
This is a mixed conditional sentence. It uses past perfect in the if-clause ('If I had left early...') and would/wouldn't + base verb in the main clause to describe a present result of a past event: 'I wouldn't be sitting here now'.
یہ ایک مخلوط شرطیہ جملہ (mixed conditional) ہے۔ ماضی کے فیصلے کا اثر اب دکھانے کے لیے 'wouldn't be' استعمال ہوگا۔

- b. Age-Specific Fertility Rate: 3. Has modal value between 20 and 25
- c. Net Reproduction Rate: 2. Affected by mortality rates
- d. Maternal Mortality Rate: 4. Is measured per 1000 live births.

Which of the pairs given above is/are correctly matched?
Explanation
Matches: GRR (Gross Reproduction Rate) measures daughters born per woman without considering mortality (a-5). ASFR usually peaks in age group 20-25 (b-3). NRR is NRR = GRR * survival rate, hence affected by mortality (c-2). MMR in this specific matching maps to 4. Correct match is a-5, b-3, c-2, d-4.
صحیح جوڑے مندرجہ ذیل ہیں: GRR کا تعلق بیٹیوں کی پیدائش کی شرح سے ہے (a-5)؛ ASFR کا موڈل گروپ 20-25 عمر کے درمیان ہوتا ہے (b-3)؛ NRR پر شرح اموات اثر انداز ہوتی ہے (c-2)۔ یعنی آپشن C درست ہے۔

- c. The expansion of (2+x)3(2+x)^3 using binomial theorem is 8+6x+12x2+x38+6x+12x^2+x^3.
- d. The number of ways 3 boys and 3 girls can sit in a row is 360.

Which of the following statements is/are correct?
Explanation
Statement a is correct (PEPPER has 6 letters: 3 P's, 2 E's, 1 R. Arrangements = 6!/(3!2!)=606! / (3! 2!) = 60). Statement b is correct (order does not matter, so combination (203)\binom{20}{3} is used). Statement c is incorrect (expansion is 8+12x+6x2+x38 + 12x + 6x^2 + x^3). Statement d is incorrect (6 people in a row can sit in 6!=7206! = 720 ways). Thus, a and b are correct.
بیان a درست ہے (PEPPER لفظ کے حروف کو ترتیب دینے کے طریقے = 60)۔ بیان b بھی درست ہے (کمیٹی کے لیے مجموعہ C کا استعمال)۔ اس لیے 'a' اور 'b' صحیح ہیں۔

- d. The limit definition of a derivative for a function f(x)f(x) is limh0f(x+h)f(x)h\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}.

Which of the following statements is/are correct?
Explanation
Statement c is correct (standard exponential limit = 1). Statement d is correct (definition of derivative). Statement a is incorrect (limit is 2). Statement b is incorrect (derivative of 1/x1/x is 1/x2-1/x^2, not 1/x21/x^2). Thus, c and d are correct.
بیان c درست ہے (معیاری ایکسپونینشل لیمٹ 1 ہوتی ہے)۔ بیان d بھی درست ہے (ڈیریویٹیو کی لیمٹ تعریف)۔ لہذا 'c' اور 'd' صحیح بیانات ہیں۔

- d. F={(x,y)F=\{(x,y)\in\mathbb{R}×\times\mathbb{R}:y=x2}: y=x^2\}

Matches:
- 1. FF={(x,z)F \circ F = \{(x,z)\in\mathbb{R}×\times\mathbb{R}:z=4x+3}: z=4x+3\}
- 2. F is increasing on (0,)(0,\infty) but not on $\mathbb{R}
- 3$. F is one-one but not onto
- 4. Range of F=[2,)F = [-2,\infty) (assuming y=x22y=x^2-2 in the paper's original intended equation)
- 5. F is not a function

Which of the pairs given above is/are correctly matched?
Explanation
F in (b) is a circle equation, which is not a function (b-5). F in (c) has F(F(x))=2(2x+1)+1=4x+3F(F(x)) = 2(2x+1)+1 = 4x+3 (c-1). F in (d) is y=x2y=x^2, which is increasing on positive real numbers but not on the whole real line (d-2). This makes D (a-4, b-5, c-1, d-2) the correct match.
صحیح جوڑے مندرجہ ذیل ہیں: دائرے کی مساوات فنکشن نہیں ہوتی (b-5)؛ لکیری فنکشن کی ترکیب 4x+3 ہے (c-1)؛ اور پیराबولا صرف مثبت طرف بڑھتا ہے (d-2)۔ اس طرح آپشن D درست ہے۔

How much of 0.6N NaOH must be added to 750 mL 0.2N NaOH in order to prepare a solution of 0.3N?
Explanation
Using the concentration equation N1V1 + N2V2 = N3V3: Let V1 be the volume of 0.6N NaOH. V2 = 750 mL, N2 = 0.2N, N3 = 0.3N, V3 = (V1 + 750). Hence, 0.6V1 + 0.2750 = 0.3(V1 + 750) => 0.6V1 + 150 = 0.3V1 + 225 => 0.3V1 = 75 => V1 = 250 mL.
مساوات N₁V₁ + N₂V₂ = N₃(V₁ + V₂) کا استعمال کرتے ہوئے: 0.6V₁ + 0.2750 = 0.3*(V₁ + 750) => 0.6V₁ + 150 = 0.3V₁ + 225 => 0.3V₁ = 75 => V₁ = 250 mL۔ اس طرح 250 ملی لیٹر محلول درکار ہے۔

Two bicycles were sold for Rs. 3,990 each, gaining 5% on one and losing 5% on the other. The gain or loss percent on the whole transaction is
Explanation
When two identical items are sold at the same price, with one transaction yielding x% gain and the other x% loss, the overall transaction always results in a loss of (x/10)^2 percent. Here, Loss % = (5/10)^2 = 0.25% loss.
جب دو چیزیں یکساں قیمت پر بیچی جائیں، ایک پر 5% منافع اور دوسری پر 5% نقصان ہو، تو مجموعی طور پر ہمیشہ نقصان ہوگا: (5/10)2=0.25%(5/10)^2 = 0.25\% نقصان۔

Alloy X consists of gold and silver in the ratio of 3:5, while Alloy Y consists of gold and silver in the ratio of 5:7. If 2/3 volume of Alloy X and 1/3 volume of Alloy Y are mixed to form a new alloy Z, what will be the ratio of gold to silver in alloy Z?
Explanation
Gold in X = 3/8, Silver in X = 5/8. Gold in Y = 5/12, Silver in Y = 7/12.
In Z:
Gold = (2/3 3/8) + (1/3 5/12) = 1/4 + 5/36 = 14/36
Silver = (2/3 5/8) + (1/3 7/12) = 5/12 + 7/36 = 22/36
Ratio = 14/36 : 22/36 = 7:11.
الائے X میں سونا = 3/8، چاندی = 5/8۔ الائے Y میں سونا = 5/12، چاندی = 7/12۔

In a hockey championship, there are 153 matches played. Every two teams played one match with each other. The number of teams participating in the championship is:
Explanation
If there are n teams, the number of matches is given by the combination formula nC2 = n(n-1)/2.
So, n(n-1)/2 = 153 => n(n-1) = 306.
Solving the quadratic equation: 18 * 17 = 306. Thus, n = 18.
اگر ٹیموں کی تعداد n ہو تو میچوں کی تعداد n(n-1)/2 ہوگی۔
n(n-1)/2 = 153 => n(n-1) = 306۔ 18 * 17 = 306 ہوتا ہے، اس طرح حصہ لینے والی ٹیموں کی تعداد 18 ہے۔ (JKSSB کی آفیشل کی کے مطابق 18 کا آپشن فائنل تھا)۔

One-third of the boys and one-half of the girls of a college participated in a social work project. If the number of participating students is 300 out of which 100 are boys, what is the total number of students in the college?
Explanation
Participating boys = 100. Since this is 1/3 of the total boys (B), B/3 = 100 => B = 300. Participating girls = 300 - 100 = 200. Since this is 1/2 of the total girls (G), G/2 = 200 => G = 400. Total students = B + G = 300 + 400 = 700.
شامل لڑکے = 100، جو کل لڑکوں کا 1/3 ہیں، لہذا کل لڑکے = 300۔ شامل لڑکیاں = 300 - 100 = 200، جو کل لڑکیوں کا نصف (1/2) ہیں، لہذا کل لڑکیاں = 400۔ کالج کے کل طلبہ کی تعداد = 300 + 400 = 700 ہے۔

اتوار سے شروع ہونے والے 30 دن کے مہینے میں 5 اتوار اور 25 عام دن ہوتے ہیں۔ اتوار کے کل زائرین = 5 510 = 2550۔ دیگر دنوں کے زائرین = 25 240 = 6000۔ کل زائرین = 8550۔ یومیہ اوسط = 8550 / 30 = 285 زائرین۔

A television manufacturer earns 20% profit by selling each T.V. set for Rs. 14400. If the production cost is increased by 15%, what should be the new selling price of a set so as to gain 15%?
Explanation
CP of TV = 14400 / 1.20 = Rs. 12000. New CP = 12000 1.15 = Rs. 13800. New SP for 15% profit = 13800 1.15 = Rs. 15870.
ٹی وی کی لاگت قیمت = 14400 / 1.20 = 12000 روپے۔ لاگت میں 15% اضافہ ہونے پر نئی قیمت = 13800 روپے۔ 15% منافع حاصل کرنے کے لیے نئی فروخت قیمت = 13800 * 1.15 = 15870 روپے۔

Explanation
Note: The transcribed equation had a typo '412' which is corrected to '4 - 12'. Interchange 'x' and '-': 171 / 3 16 + 72 - 4 - 12 = 572 => 57 16 + 72 - 16 = 912 + 72 - 16 = 968 - 16 = 968 - 396? Wait, if 412 is kept: 171 / 3 16 + 72 - 412 = 572 => 57 16 + 72 - 412 = 912 + 72 - 412 = 572. The equation is correct. Hence we interchange 'x' and '-'.
درست مساوات کے لیے ضرب (x) اور تفریق (-) کو آپس میں تبدیل کرنا ہوگا۔ مساوات بن جائے گی: 171 ÷ 3 × 16 + 72 - 412 = 572۔ حل کرنے پر: 912 + 72 - 412 = 572، جو کہ درست ہے۔

The average weight of a group of seven boys is 56 kg. The individual weights (in kg) of six of them are 52, 57, 55, 60, 59 and 55. Find the weight of the seventh boy.
Explanation

Explanation
Let original class sizes be 2x, 3x, 4x. Total = 9x. After increase of 12: (2x+12)/(3x+12) = 8/11 => 22x + 132 = 24x + 96 => 2x = 36 => x = 18. Total = 9 * 18 = 162.
پہلے طلبہ کا تناسب 2x:3x:4x تھا۔ کل تعداد 9x۔ 12 طلبہ کے اضافے کے بعد: (2x+12)/(3x+12) = 8/11۔ حل کرنے پر 22x + 132 = 24x + 96 یعنی 2x = 36، اس لیے x = 18۔ آغاز میں طلبہ کی کل تعداد = 9 × 18 = 162۔

Consider the following statements:

Statement (I): In AM systems the modulation index (0 < m < 1) should be high.
Statement (II): The higher the value of m, the greater the power in the sidebands.

Choose the correct option.
Explanation
In AM systems, the sideband power is given by Pc(m2/2)P_c(m^2/2). A higher modulation index 'm' increases the sideband power, leading to higher efficiency. Thus, statement II is true and is the correct explanation for statement I.
ایمپلی ٹیوڈ ماڈیولیشن (AM) میں سائیڈ بینڈ پاور کا فارمولا Pc(m^2/2) ہے۔ ماڈیولیشن انڈیکس 'm' جتنا زیادہ ہوگا، سائیڈ بینڈ میں اتنی ہی زیادہ طاقت ہوگی اور سگنل زیادہ موثر ہوگا۔ لہذا دونوں بیانات درست ہیں اور دوسرا بیان پہلے کی صحیح وضاحت کرتا ہے۔

Explanation
The peak voltage of the modulating signal alone is Vm=mimesVc=0.8imes15extkV=12extkVV_m = m imes V_c = 0.8 imes 15 ext{ kV} = 12 ext{ kV} (Option B).

Explanation
Total profit = 1000. A's profit = 500, B's profit = 300. C's profit = 1000 - (500 + 300) = 200. Profit ratio is A:B:C = 500:300:200 = 5:3:2. Since capital ratio equals profit ratio, A's capital (5 parts) = 10,000 => 1 part = 2,000. C's capital (2 parts) = 2 * 2,000 = Rs. 4,000.
کل منافع = 1000۔ A کا منافع = 500، B کا = 300۔ C کا منافع = 200۔ تناسب = 5:3:2۔ چونکہ منافع کا تناسب سرمایہ کاری کے برابر ہے، اس لیے A کا سرمایہ (5 حصے) = 10,000 یعنی 1 حصہ = 2,000۔ C کا سرمایہ (2 حصے) = 2 × 2000 = 4,000 روپے ہوگاُ۔

Find the error in the parts of the sentence: "Everyone misses a class from time to time (A) / but no one (B) / skip an examination (C) / No error (D)"
Explanation
The error is in Part C. The pronoun 'no one' is singular and must be followed by a singular verb 'skips', not the plural 'skip'.

A 5-foot-long cylindrical pipe has an inner diameter of 6 feet and an outer diameter of 8 feet. If the total surface area (inside and out, including the ends) is kπk\pi, what is the value of k?
Explanation
Inner radius r = 3, outer radius R = 4, height h = 5. Outer lateral area = 2πRh = 40π. Inner lateral area = 2πrh = 30π. End rings area = 2 π(R^2 - r^2) = 2 π(16 - 9) = 14π. Total area = 40π + 30π + 14π = 84π. Thus k = 84.
اندرونی رداس r = 3، بیرونی R = 4، اونچائی h = 5۔ بیرونی سطح کا رقبہ = 40π، اندرونی = 30π۔ دونوں سروں کے حلقوں کا رقبہ = 14π۔ کل رقبہ = 84π، یعنی k = 84۔

From a rope of 30 meters long, a person cuts off as many pieces as possible, each 3163\frac{1}{6} meters long. What fraction of the whole will be left? (Note: Options list the remaining length in meters)
Explanation
Length of 1 piece = 19/6 m. Number of pieces = floor(30 / (19/6)) = floor(180/19) = 9. Total length cut = 9 * 19/6 = 57/2 = 28.5 m. Remaining length = 30 - 28.5 = 1.5 m. Note that 1.5 m is equivalent to 9/6 meters, which is option A. The actual fraction of the whole rope is 1.5 / 30 = 1/20.
ایک ٹکڑے کی لمبائی = 19/6 میٹر۔ کل ٹکڑے = 9۔ کٹی ہوئی رسی = 28.5 میٹر۔ باقی بچنے والی لمبائی = 1.5 میٹر، جو کہ 9/6 کے برابر ہے (آپشن A)۔ پوری رسی کا فریکشن 1.5/30 = 1/20 ہے۔

Explanation
In conic sections, if the section plane makes an angle α\alpha with the axis of the cone such that θ<α<90\theta < \alpha < 90^\circ (where θ\theta is the semi-vertical angle, i.e., half of the apex angle), the resulting section is an Ellipse.

Explanation
Stopping distance s=u22as = \frac{u^2}{2a}. For Bus 1: s1=2022×5=40 ms_1 = \frac{20^2}{2 \times 5} = 40 \text{ m}. For Bus 2: s2=1022×5=10 ms_2 = \frac{10^2}{2 \times 5} = 10 \text{ m}.

What sum of money will amount to Rs. 520\text{Rs. } 520 in 55 years and to Rs. 568\text{Rs. } 568 in 77 years at the same rate of simple interest?
Explanation
Amount in 77 years = P+7I=568P + 7I = 568.
Amount in 55 years = P+5I=520P + 5I = 520.
Subtracting the two equations: 2I=48    I=242I = 48 \implies I = 24 per year.
Simple interest for 55 years = 5×24=1205 \times 24 = 120.

The concentration of [OH][\text{OH}^-] ion in a water sample is measured as 17 mg/L17\text{ mg/L} at 25 degrees Celsius. What is the pH of water sample?
Explanation
Molecular weight of [OH]=17 g/mol=17,000 mg/mol[OH^-] = 17\text{ g/mol} = 17,000\text{ mg/mol}. Molarity of [OH]=17 mg/L17,000 mg/mol=103 mol/L[OH^-] = \frac{17\text{ mg/L}}{17,000\text{ mg/mol}} = 10^{-3}\text{ mol/L}. Therefore, pOH=log10[OH]=log10(103)=3pOH = -\log_{10}[OH^-] = -\log_{10}(10^{-3}) = 3. Since pH+pOH=14pH + pOH = 14, pH=143=11pH = 14 - 3 = 11.
[OH]=17 mg/L=103 M    pOH=3    pH=143=11[OH^-] = 17\text{ mg/L} = 10^{-3}\text{ M} \implies pOH = 3 \implies pH = 14 - 3 = 11۔

Read the following passage carefully to answer the question:
"In an era marked by environmental concerns and the urgent need for action against climate change, sustainable energy has emerged as a beacon of hope. Sustainable energy, also known as renewable energy, refers to energy sources that are naturally replenished and have minimal impact on our environment. The various energy sources are solar, wind, hydroelectric, geothermal, and biomass. The adoption of sustainable energy holds immense promise in addressing some of the most pressing challenges facing humanity today. One of its primary goals is to reduce dependence on finite fossil fuels, such as coal, oil, and natural gas, which contribute significantly to greenhouse gas emissions and air pollution. By transitioning to renewable sources, we can mitigate the harmful effects of climate change, improve air quality, and safeguard the health of both people and the planet.

Furthermore, it promotes security by diversifying the supply of energy and by reducing vulnerability to geopolitical conflicts and fluctuations in fossil fuel prices. It also fosters economic growth and job creation, as the renewable energy sector continues to expand and innovate. However, the pursuit of sustainable energy is closely linked to various global goals and initiatives. The United Nations Sustainable Development Goals (SDGs), emphasize the importance of ensuring access to reliable, sustainable, and modern energy for all. Additionally, the Paris Agreement aims to limit the increase in the global average temperature to well below 2°C above pre-industrial level. Governments, businesses, and individuals must work together to accelerate the transition to sustainable energy. This involves investing in research and development, implementing supportive policies and regulations, enhancing energy efficiency, and promoting public awareness and education."

Read the passage given below to answer the question:
"The Stone Age was a period of history that began approximately 2 million BC and lasted until 3000 BC, deriving its name from the stone tools and weapons discovered by modern scientists. This period was divided into the Paleolithic, Mesolithic and Neolithic periods. During the First Age (2 million to 8000 BC), the first hatchets and the use of fire for heating and cooking were developed.

As a result of the Ice Age, which evolved about 1 million years into the Paleolithic era, humans were forced to shelter in caves, wear clothing, and develop new tools. During the Mesolithic period (8000 to 6000 BC), people made crude pottery and took dogs for hunting with the first fish hook and developed a bow and arrow, which was used until the fourteenth century BC. The Neolithic period (6000 to 3000 BC) saw mankind domesticating sheep, goats, pigs and cattle, becoming less nomadic than in earlier periods, establishing permanent settlements and forming governments."

A boat moving upstream takes 8 hours 48 minutes to cover a distance while it takes 4 hours to return to the starting point, downstream. What is the ratio of the speed of boat in still water to that of water current?
Explanation
Upstream time tu=8 h 48 min=8.8 h=445 ht_u = 8\text{ h } 48\text{ min} = 8.8\text{ h} = \frac{44}{5}\text{ h}. Downstream time td=4 ht_d = 4\text{ h}. Since distance is equal: (uv)×445=(u+v)×4    11(uv)=5(u+v)    11u11v=5u+5v    6u=16v    uv=166=83(u-v) \times \frac{44}{5} = (u+v) \times 4 \implies 11(u-v) = 5(u+v) \implies 11u - 11v = 5u + 5v \implies 6u = 16v \implies \frac{u}{v} = \frac{16}{6} = \frac{8}{3}. Ratio is 8:3.
فاصلہ برابر ہونے کی وجہ سے: 11(uv)=5(u+v)    6u=16v    u:v=8:311(u-v) = 5(u+v) \implies 6u = 16v \implies u:v = 8:3 ہے۔

The volume of a cube with side 'll' and the volume of a sphere with radius 'rr' are equal. Both the cube and sphere are composed of the same material and are being cast. What is the ratio of the solidification time of the cube to that of the sphere?
Explanation
According to Chvorinov's Rule: ts(VA)2t_s \propto \left(\frac{V}{A}\right)^2. Since Vcube=VsphereV_{cube} = V_{sphere}, the ratio of solidification times is \frac{t_{cube}}{t_{sphere}} = \left(\frac{A_{sphere}}{A_{cube}} ight)^2 = \left(\frac{4\pi r^2}{6 l^2}\right)^2 = \left(\frac{4\pi}{6}\right)^2 \left(\frac{r}{l}\right)^4.

2535📚🔬 Space Science & PhysicsSatellite Launch Trajectories & Orbital Mechanics
Assertion (A): Artificial Satellites are always launched from the earth in the eastwards direction.
Reason (R): The earth rotates from west to east and so the satellite attains the escape velocity.
Choose the correct option:
Explanation
Assertion (A) is correct: Satellites are launched eastward to harness Earth's eastward rotational linear speed boost (maximum near the equator). Reason (R) is incorrect because Earth's rotational boost helps attain orbital insertion velocity (~7.8 km/s), NOT escape velocity (11.2 km/s).
دعویٰ (A) درست ہے کہ سیٹلائٹس مشرق کی سمت داغے جاتے ہیں، لیکن وجہ (R) غلط ہے کیونکہ یہ مداروی رفتار کے لیے ہوتا ہے نہ کہ فرار کی رفتار (Escape velocity) کے لیے۔

2753📚🧮 Quantitative AptitudeProblems on Trains: Speed Conversion
Two trains A and B traveling at constant speeds cross an electric pole in 20 s and 30 s respectively. The length of train A is 240 m and that of train B is 300 m. What is the difference in the speeds of the two trains in km/h?
Explanation
Speed of Train A =240 m20 s=12 m/s= \frac{240\text{ m}}{20\text{ s}} = 12\text{ m/s}. Speed of Train B =300 m30 s=10 m/s= \frac{300\text{ m}}{30\text{ s}} = 10\text{ m/s}. Difference =1210=2 m/s=2×185=365=7.2 km/h= 12 - 10 = 2\text{ m/s} = 2 \times \frac{18}{5} = \frac{36}{5} = 7.2\text{ km/h}.
رفتار کا فرق =(1210) m/s=2×3.6=7.2 km/h= (12 - 10)\text{ m/s} = 2 \times 3.6 = 7.2\text{ km/h}۔

The logic problem presents three true statements: Fact 1, Fact 2, and Fact 3. Then, three more statements (labelled I, II, and III) are given. Determine which of these, if any, is also a fact based solely on the information given in the first three facts.

Fact 1: Jasmeen has four children. Fact 2: Two of the children have blue eyes, and two have brown eyes.
Fact 3: Half of the children are girls. Given that the first three statements are facts, which of the following statements must also be true? I: At least one girl has blue eyes.
II: Two of the children are boys. III: The boys have brown eyes.

Choose the correct option:
Explanation
From Fact 1 (4 children) and Fact 3 (half are girls = 2 girls), it is a mathematical certainty that the remaining 2 children are boys. Therefore, Statement II must be true. Statements I and III are possibilities but cannot be proven definitively. Hence, II only is a known fact.
तथ्य 1 (4 बच्चे) और तथ्य 3 (आधी लड़कियाँ = 2 लड़कियाँ) से यह 100% निश्चित है कि शेष 2 बच्चे लड़के हैं। अतः केवल कथन II निश्चित रूप से सत्य है।

Let total profit be PP.
After 5% charity, distributable profit =0.95P= 0.95P.
Ratio of A to B is 3:23 : 2, so A's fraction is 35\frac{3}{5}:
A’s share=35×0.95P=0.57P=912\text{A's share} = \frac{3}{5} \times 0.95P = 0.57P = 912
P=9120.57=9120057=1600 Rs.P = \frac{912}{0.57} = \frac{91200}{57} = 1600\text{ Rs}.

A train increases its normal speed by 12.5% and reaches its destination 20 minutes earlier. What is the actual (normal) time taken by the train on the journey?
Explanation
Increase in speed =12.5%=18= 12.5\% = \frac{1}{8}.
New speed =S(1+18)=98S= S \left(1 + \frac{1}{8}\right) = \frac{9}{8}S.
Since distance is constant, time is inversely proportional to speed:
New time T=89T\text{New time } T' = \frac{8}{9}T
Time saved =T89T=T9=20 minutes= T - \frac{8}{9}T = \frac{T}{9} = 20\text{ minutes}
T=9×20=180 minutes=3 hours.T = 9 \times 20 = 180\text{ minutes} = 3\text{ hours}.
गति में 12.5%=1812.5\% = \frac{1}{8} की वृद्धि     \implies नई गति =98= \frac{9}{8} मूल गति।
नया समय =89= \frac{8}{9}मूल समय।

In an examination, 30% and 35% of students, respectively, failed in History and Geography while 27% of students failed in both subjects. If the number of students passing the examination is 372, find the total number of students who appeared in the examination.
Explanation
Percentage of students failing in at least one subject:
%Failed=n(H)+n(G)n(HG)=30%+35%27%=38%\%\text{Failed} = n(H) + n(G) - n(H \cap G) = 30\% + 35\% - 27\% = 38\%
Percentage of students passing both subjects:
%Passed=100%38%=62%\%\text{Passed} = 100\% - 38\% = 62\%
Given 62%=37262\% = 372:
Total Students=3720.62=600.\text{Total Students} = \frac{372}{0.62} = 600.
कुल अनुत्तीर्ण छात्र %=30+3527=38%\% = 30 + 35 - 27 = 38\%
उत्तीर्ण छात्र %=10038=62%\% = 100 - 38 = 62\%
कुल छात्र =37262×100=600= \frac{372}{62} \times 100 = 600

The average salary of all the workers in a workshop is Rs. 10,000. The average salary of 6 technicians is Rs. 15,000 and the average salary of the rest is Rs. 8000. The total number of workers in the workshop is:
Explanation
Let total workers be NN.
Total salary =10000N= 10000N.
Salary of 6 technicians =6×15000=90000= 6 \times 15000 = 90000.
Salary of remaining (N6)(N - 6) workers =(N6)×8000= (N - 6) \times 8000.
Equation:
90000+8000(N6)=10000N90000 + 8000(N - 6) = 10000N
90000+8000N48000=10000N90000 + 8000N - 48000 = 10000N
42000=2000N    N=21.42000 = 2000N \implies N = 21.
माना कुल कर्मचारी NN हैं।
6×15000+(N6)×8000=10000N6 \times 15000 + (N - 6) \times 8000 = 10000N
42000=2000N    N=2142000 = 2000N \implies N = 21 कर्मचारी।

3141📚Quantitative Aptitude & Basic MathematicsSimple and Compound Interest
A sum of money amounts to Rs. 9,800 after 5 years and Rs. 12,005 after 8 years at the same rate of simple interest. What is the rate of interest per annum?
Explanation
Simple Interest for 3 years (between Year 5 and Year 8):
SI3 yrs=120059800=2205\text{SI}_{3\text{ yrs}} = 12005 - 9800 = 2205
Simple Interest for 1 year:
SI1 yr=22053=735\text{SI}_{1\text{ yr}} = \frac{2205}{3} = 735
Principal PP:
P=9800(5×735)=98003675=6125P = 9800 - (5 \times 735) = 9800 - 3675 = 6125
Rate of Interest RR:
R=SI1 yrP×100=7356125×100=12%.R = \frac{\text{SI}_{1\text{ yr}}}{P} \times 100 = \frac{735}{6125} \times 100 = 12\%.
3 वर्ष का साधारण ब्याज =120059800=2205= 12005 - 9800 = 2205 रुपये     1\implies 1 वर्ष का ब्याज =735= 735 रुपये।
मूलधन (P)=9800(5×735)=6125(P) = 9800 - (5 \times 735) = 6125 रुपये।
ब्याज दर (R)=7356125×100=12%(R) = \frac{735}{6125} \times 100 = 12\%

3142📚Quantitative Aptitude & Basic MathematicsSimple and Compound Interest
The difference between simple interest and compound interest (interest is compounded half yearly) on a sum at the rate of 25% per annum for one year is Rs. 4,575. What will be the principal?
Explanation
For half-yearly compounding over 1 year:
- Number of conversion periods n=2n = 2
- Rate per half-year r=252%=12.5%=18r = \frac{25}{2}\% = 12.5\% = \frac{1}{8}
Difference formula for 2 periods:
Diff=P(r100)2=P(18)2=P64\text{Diff} = P \left(\frac{r}{100}\right)^2 = P \left(\frac{1}{8}\right)^2 = \frac{P}{64}
Given Diff=4575\text{Diff} = 4575:
P=4575×64=292,800 Rs.P = 4575 \times 64 = 292,800\text{ Rs}.
अर्धवार्षिक दर r=12.5%=18r = 12.5\% = \frac{1}{8}(2 अवधियाँ)।
अंतर = P \times (\frac{1}{8})^2 = \frac{P}{64} = 4575 रुपये
P = 4575 \times 64 = 2,92,800 रुपये।

If x1x=6x - \frac{1}{x} = 6, then what is the value of (x+1x)\left(x + \frac{1}{x}\right)?
Explanation
Using the algebraic identity (x+1x)2=(x1x)2+4\left(x + \frac{1}{x}\right)^2 = \left(x - \frac{1}{x}\right)^2 + 4:
(x+1x)2=62+4=36+4=40\left(x + \frac{1}{x}\right)^2 = 6^2 + 4 = 36 + 4 = 40
x+1x=40=4×10=210x + \frac{1}{x} = \sqrt{40} = \sqrt{4 \times 10} = 2\sqrt{10}
(Note: Option standard evaluates to $2\sqrt{10}$, listed in key under equivalent root options).
(x+1x)2=(x1x)2+4=36+4=40    x+1x=40=210\left(x + \frac{1}{x}\right)^2 = \left(x - \frac{1}{x}\right)^2 + 4 = 36 + 4 = 40 \implies x + \frac{1}{x} = \sqrt{40} = 2\sqrt{10}

The top of a 15-metre high tower makes an angle of depression of 6060^\circ with the bottom of an electric pole and an angle of depression of 3030^\circ with the top of the pole. What is the height of the electric pole?
Explanation
Let the height of the tower be H=15 mH = 15\text{ m}, height of the pole be hh, and horizontal distance between them be dd.
From the bottom of the pole:
tan60=15d    3=15d    d=153=53 m\tan 60^\circ = \frac{15}{d} \implies \sqrt{3} = \frac{15}{d} \implies d = \frac{15}{\sqrt{3}} = 5\sqrt{3}\text{ m}
From the top of the pole to top of tower:
tan30=15hd    13=15h53\tan 30^\circ = \frac{15 - h}{d} \implies \frac{1}{\sqrt{3}} = \frac{15 - h}{5\sqrt{3}}
15h=5    h=155=10 metres.15 - h = 5 \implies h = 15 - 5 = 10\text{ metres}.
मीनार की ऊंचाई = 15 मी।
tan60\tan 60^\circ = 15d\frac{15}{d}     d=5\implies d = 53\sqrt{3} मी।
tan30\tan 30^\circ = 15hd\frac{15 - h}{d}     \implies \frac{1}{\sqrt{3}} = \frac{15 - h}{5\sqrt{3}}     15h=5\implies 15 - h = 5     h=10\implies h = 10 मीटर।

Explanation
Base circumference:
2πr=44    2×227×r=44    r=7 cm2\pi r = 44 \implies 2 \times \frac{22}{7} \times r = 44 \implies r = 7\text{ cm}
Volume of the cylinder:
V=πr2h=227×72×25=22×7×25=3850 cm3V = \pi r^2 h = \frac{22}{7} \times 7^2 \times 25 = 22 \times 7 \times 25 = 3850\text{ cm}^3
Converting to litres (1 litre=1000 cm31\text{ litre} = 1000\text{ cm}^3):
Capacity=38501000=3.85 litres.\text{Capacity} = \frac{3850}{1000} = 3.85\text{ litres}.
2\pi r = 44 \implies r = 7 सेमी।

LCM(a,b) = 437
LCM(b,c) = 667
LCM(a,c) = 551
Find the value of a + b + c
Explanation
Since a,b,ca, b, c are pairwise co-prime prime factors:
- ab=437=19×23ab = 437 = 19 \times 23
- bc=667=23×29bc = 667 = 23 \times 29
- ac=551=19×29ac = 551 = 19 \times 29
Thus a=19,b=23,c=29a = 19, b = 23, c = 29.
a+b+c=19+23+29=71.a + b + c = 19 + 23 + 29 = 71.
ab=19×23ab = 19 \times 23, bc=23×29bc = 23 \times 29, ac=19×29ac = 19 \times 29
अतः a=19,b=23,c=29    a+b+c=71a = 19, b = 23, c = 29 \implies a + b + c = 71

Explanation
Depreciated value after 3 years:
V3=45000×(10.08)3=45000×(0.92)3=45000×0.778688=35040.96 RsV_3 = 45000 \times (1 - 0.08)^3 = 45000 \times (0.92)^3 = 45000 \times 0.778688 = 35040.96\text{ Rs}
Given V3=0.45×PoriginalV_3 = 0.45 \times P_{\text{original}}:
Poriginal=35040.960.4577,868.877,869 Rs.P_{\text{original}} = \frac{35040.96}{0.45} \approx 77,868.8 \approx 77,869\text{ Rs}.
3 वर्ष बाद मूल्य =45000×(0.92)3=35040.96= 45000 \times (0.92)^3 = 35040.96 रुपये।

In her house, Anita installed 4 new fans with each fan consuming 70 W in addition to the 6 fans already installed with each fan consuming 50 W. She uses the new fans for 10 hours daily and the older fans for 20 hours daily. Calculate the electricity bill for one month (30 days) if the cost of one unit of electricity is Rs. 10.
Explanation
Daily energy consumption:
- New fans: 4×70 W×10 h=2800 Wh=2.8 kWh4 \times 70\text{ W} \times 10\text{ h} = 2800\text{ Wh} = 2.8\text{ kWh}
- Old fans: 6×50 W×20 h=6000 Wh=6.0 kWh6 \times 50\text{ W} \times 20\text{ h} = 6000\text{ Wh} = 6.0\text{ kWh}
- Daily total =2.8+6.0=8.8 kWh (units)= 2.8 + 6.0 = 8.8\text{ kWh (units)}
- Monthly units (30 days) =8.8×30=264 units= 8.8 \times 30 = 264\text{ units}

3352📚Basic Electrical Engineering & Circuit TheoryResistance & Resistivity
The resistance of the wire is 10 ohms. What will be the effect on resistance and resistivity of the wire, if the wire is stretched to 10 times its original length?
Explanation
When a wire of length LL and area AA is stretched to 10L10L, its volume V=ALV = A \cdot L remains constant, so its cross-sectional area becomes A/10A/10.
New resistance R=ρ10LA/10=100(ρLA)=100RR' = \rho \frac{10L}{A/10} = 100 \left(\rho \frac{L}{A}\right) = 100 R.
Resistivity (ρ\rho) is an intensive intrinsic material property and remains completely unchanged.
तार की लंबाई 10 गुना खींचने पर अनुप्रस्थ काट क्षेत्रफल 1/101/10 हो जाता है, जिससे प्रतिरोध 102=10010^2 = 100 गुना बढ़ जाता है, जबकि प्रतिरोधकता (Resistivity) अपरिवर्तित रहती है।

At the midpoint, when currents are parallel (same direction), fields oppose: B=k(I1I2)=70 μTB = k(I_1 - I_2) = 70\ \mu\text{T}.
When anti-parallel (opposite direction), fields add: B=k(I1+I2)=140 μTB' = k(I_1 + I_2) = 140\ \mu\text{T}.

3399📚TransformersSeparation of Core Losses in Transformers
In a single-phase transformer, the total iron loss is 3000 W at a nominal voltage of 500 V and a frequency of 50 Hz. The total iron loss is 1200 W at 250 V and 25 Hz. At nominal voltage and frequency, the hysteresis and eddy current losses are:
Explanation
When V/f=constantV/f = \text{constant} (500/50=250/25=10500/50 = 250/25 = 10), maximum flux density BmB_m is constant:
Total core loss Pi=Af+Bf2P_i = A f + B f^2.
- At 50 Hz: 50A+2500B=3000    A+50B=6050A + 2500B = 3000 \implies A + 50B = 60
- At 25 Hz: 25A+625B=1200    A+25B=4825A + 625B = 1200 \implies A + 25B = 48
Subtracting gives 25B=12    B=0.4825B = 12 \implies B = 0.48.
Then A=6050(0.48)=6024=36A = 60 - 50(0.48) = 60 - 24 = 36.
At 50 Hz nominal:
- Hysteresis Loss Ph=Af=36×50=1800 WP_h = A f = 36 \times 50 = 1800\text{ W}
- Eddy Current Loss Pe=Bf2=0.48×2500=1200 WP_e = B f^2 = 0.48 \times 2500 = 1200\text{ W}.
V/fV/f नियत होने पर Pi=Af+Bf2P_i = A f + B f^2
समीकरण हल करने पर A=36,B=0.48A = 36, B = 0.48
50 Hz पर: हिस्टैरिसीस हानि =1800= 1800 W तथा भंवर धारा हानि =1200= 1200 W।

3413📚Electrical Safety, Earthing & InstallationImportance of Low Earth Resistance
What happens if the earth's resistance is too high?
Explanation
If earthing resistance is too high, fault leakage currents cannot flow freely to ground, preventing protective fuses and circuit breakers from tripping, thereby leaving metal appliance chassis energized and creating severe electric shock/fire hazards.
यदि अर्थिंग प्रतिरोध बहुत अधिक हो, तो फॉल्ट करंट जमीन में नहीं जा पाता, जिससे उपकरण की बॉडी में करंट रहने से बिजली के झटके (Electric shock) का खतरा बढ़ जाता है।

3414📚Electromagnetic Induction & AC CircuitsResistive AC Circuits & Unity Power Factor
When the current is in phase with the circuit voltage, the power factor of the circuit is unity. This condition occurs in which type of circuit?
Explanation
In a purely resistive AC circuit (and an RLC circuit at series resonance), current and voltage are exactly in phase (ϕ=0\phi = 0^\circ), so the power factor is cos0=1.0\cos 0^\circ = 1.0 (Unity).

```c
#include <stdio.h>
int main() {
int arr[3] = {1, 2, 3};
printf("%d
", 2[arr]);
return 0;
}
```
Explanation
In C, array subscript notation is commutative: `arr[2]` is equivalent to `(arr + 2)`, which is identical to `(2 + arr)` or `2[arr]`. Since `arr[2] == 3`, the code outputs `3`.
C भाषा में ऐरे सबस्क्रिप्ट क्रम-विनिमेय (commutative) होता है: `2[arr]` और `arr[2]` दोनों `*(arr + 2)` के बराबर हैं। अतः मान `3` प्रिंट होगा।

3425📚C Programming & Data StructuresControl Structures & Null Statements
What will be the output of this code?

```c
#include <stdio.h>
int main() {
int a = 5;
if (a == 5)
printf("Hello");
else;
printf("World!");
return 0;
}
```
Explanation
Since `a == 5` is true, `printf("Hello");` executes. The `else;` has a semicolon, making it a null statement. Thus, the subsequent statement `printf("World!");` is not part of the `else` branch and always executes. Output is `Hello World!`.
`a == 5` सत्य होने पर 'Hello' प्रिंट होता है। `else;` के बाद सेमीकोलन होने के कारण 'World!' हमेशा निष्पादित होगा। अतः आउटपुट 'Hello World!' होगा।

3426📚C Programming & Data StructuresPointers & Dereferencing in C
What is the output of the following code?

int main() {
int x = 5;
int y = 10;
int p = &x; p += y;
printf("%d %d
", x, y);
return 0;
}
```
Explanation
`p` points to `x`. `*p += y` adds the value of `y` (10) to `x` (5), making `x = 15`. `y` remains 10. Output is `15 10`.
`p` का मान `x` का पता है। `*p += y` से `x` का मान 5+10=155 + 10 = 15 हो जाता है। अतः आउटपुट `15 10` है।

```c
#include <stdio.h>
void func() {
int p = NULL; p = 10;
}
int main() {
func();
return 0;
}
```
Explanation
Dereferencing a NULL pointer (`*p = 10`) attempts to write to an invalid memory location (address 0x0), which causes an OS memory access violation resulting in a Segmentation Fault (and undefined behavior).
NULL पॉइंटर को डिरेफरेंस (`*p = 10`) करने पर मेमोरी एक्सेस उल्लंघन होता है, जिससे 'Segmentation fault' उत्पन्न होता है।

3428📚C Programming & Data StructuresStructure Padding & Memory Alignment
What is the size of the following structure?

```c
struct Test {
char a;
int b;
char c;
};
```
Explanation
Due to structure padding and 4-byte integer alignment on 32/64-bit systems:
- `char a`: 1 byte + 3 bytes padding = 4 bytes
- `int b`: 4 bytes = 4 bytes
- `char c`: 1 byte + 3 bytes tail padding = 4 bytes
Total size = 12 bytes.
स्ट्रक्चर पैडिंग और 4-बाइट एलाइनमेंट के कारण: `char a` (1 + 3 पैडिंग) + `int b` (4) + `char c` (1 + 3 पैडिंग) = 12 बाइट्स।

using namespace std;

class Base {
public:
virtual void display() { cout << "Base" << endl; }
};

void display() { cout << "Derived" << endl; }
};

int main() {
Base* b;
Derived d;
b = &d;
