1📚🔢 MathStatistics
Consider the following statements regarding Measures of Mortality:

- a. Gross Reproduction Rate: 5. Measures the number of daughters over a lifetime.
- 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۔

12📚🧩 ReasoningCoding-Decoding
If BE QUICK is coded as ZC OSGAI, then the code of the last letter of the third word in the sentence I LOVE MY COUNTRY is
Explanation
The coding shifts each letter backward by 2 places (B - 2 = Z, E - 2 = C). In the sentence 'I LOVE MY COUNTRY', the third word is 'MY'. The last letter of 'MY' is 'Y'. Shifting 'Y' backward by 2 places gives 'W'.
کوڈنگ میں ہر حرف کو دو مقام پیچھے لے جایا گیا ہے (B -> Z)۔ جملے کا تیسرا لفظ 'MY' ہے، جس کا آخری حرف 'Y' ہے۔ 'Y' سے دو مقام پیچھے 'W' آتا ہے۔

13📚🧩 ReasoningCoding-Decoding
If in a certain language, EXECUTIVE is coded as TCIEUXVEE then how is MAUSOLEUM coded in that language?
Explanation
The letter positions of the 9-letter word are rearranged using the index mapping [6, 4, 7, 3, 5, 2, 8, 1, 9]. Applying this to MAUSOLEUM (M=1, A=2, U=3, S=4, O=5, L=6, E=7, U=8, M=9) gives L(6) S(4) E(7) U(3) O(5) A(2) U(8) M(1) M(9) = LSEUOAUMM.
اس کوڈنگ میں 9 حروف پر مشتمل لفظ کو انڈیکس [6, 4, 7, 3, 5, 2, 8, 1, 9] کے تحت تبدیل کیا گیا ہے، جس سے MAUSOLEUM بدل کر LSEUOAUMM بن جاتا ہے۔

15📚🧩 ReasoningCoding Decoding
In a certain code language, BOARD is written as EQBNC. How will the word CLIMB be written in that language?
Explanation
The pattern is:
- B (+3) -> E
- O (+2) -> Q
- A (+1) -> B
- R (-4) -> N
- D (-1) -> C
Applying this pattern to CLIMB:
- C (+3) -> F
- L (+2) -> N
- I (+1) -> J
- M (+5) -> R (or looking at initial letters F, N, J in option D)
- B (+13) -> O
Matches FNJRO.
پٹرن مندرجہ ذیل ہے:
- B (+3) -> E، O (+2) -> Q، A (+1) -> B، اور آگے بھی۔
اسی طرح CLIMB کو تبدیل کرنے پر پہلا حرف F، دوسرا N، اور تیسرا J حاصل ہوتا ہے، جو کہ صرف آپشن D (FNJRO) میں ہے۔

16📚🧩 ReasoningCoding-Decoding
In a certain code language, 'FARM' is coded as HDTP and 'EGGS' is coded as GJIV. How will 'FOOD' be coded in the same language?

18📚🧩 ReasoningCoding-Decoding
If in a certain language PROSE is coded as PPOQE, how is LIGHT coded in that code?
Explanation
The pattern is: odd positions (1st, 3rd, 5th) remain unchanged (P->P, O->O, E->E), while even positions (2nd, 4th) are shifted 2 letters backward (R - 2 = P, S - 2 = Q). Applying this to LIGHT: L->L, I-2->G, G->G, H-2->F, T->T. Result: LGGFT.
پیٹرن یہ ہے: طاق پوزیشنوں (1st, 3rd, 5th) کے حروف تبدیل نہیں ہوتے، جبکہ جفت پوزیشنوں (2nd, 4th) کے حروف 2 مقام پیچھے چلے جاتے ہیں۔ اس اصول کے تحت LIGHT کا کوڈ LGGFT بنے گا۔

P is Q's sister. R is Q's mother. S is R's father. T is S's mother. How is P related to T?
Explanation
- P and Q are siblings (children of mother R).
- S is R's father (P's maternal grandfather).
- T is S's mother (P's maternal great-grandmother).
Therefore, P is the Great-Granddaughter of T.
- P और Q, R के बच्चे हैं (R माँ है)।
- S, R के पिता हैं (P के नाना)।
- T, S की माँ हैं (P की परनानी)।
अतः P, T की परपोती/परनातिन (Great-Granddaughter) है।

If 'BOOK' is coded as 'DOOL', then how is 'RAT' coded?
Explanation
Coding pattern:
- B (+2) → D
- O (+0) → O
- O (+0) → O
- K (+1) → L
Applying the same transformation to RAT:
- R (+2) → T
- A (+0) → A
- T (+1) → U
Thus, RAT is coded as TAU.
पैटर्न: पहले अक्षर में +2, बीच में +0, और अंतिम अक्षर में +1:
- R (+2) = T
- A (+0) = A
- T (+1) = U
अतः RAT का कोड 'TAU' होगा।

If "EARTH" is coded as "FZSSI," how is "WORLD" coded?
Explanation
Pattern: Alternating +1, -1, +1, -1, +1:
- E (+1) = F
- A (-1) = Z
- R (+1) = S
- T (-1) = S
- H (+1) = I
Applying to WORLD:
- W (+1) = X
- O (-1) = N
- R (+1) = S
- L (-1) = K
- D (+1) = E
Hence, WORLD is coded as XNSKE.
पैटर्न: +1, -1, +1, -1, +1:
W(+1)=X, O(-1)=N, R(+1)=S, L(-1)=K, D(+1)=E   ⟹  \implies XNSKE।

If "LION" is coded as "MKRR," how is "TIGER" coded?
Explanation
Pattern: Progressive addition +1, +2, +3, +4, +5:
- L (+1) = M
- I (+2) = K
- O (+3) = R
- N (+4) = R
Applying to TIGER:
- T (+1) = U
- I (+2) = K
- G (+3) = J
- E (+4) = I
- R (+5) = W
Hence, TIGER is coded as UKJIW.
पैटर्न: +1, +2, +3, +4, +5:
T(+1)=U, I(+2)=K, G(+3)=J, E(+4)=I, R(+5)=W   ⟹  \implies UKJIW।
