Question 40

(0.08 * 0.007) is equal to

Accepted Answer

Option C: 0.00056. 8 * 7 = 56. The decimal points are 2 places in 0.08 and 3 places in 0.007, summing up to 5 decimal places. Therefore, the result is 0.00056.

Question 41

Determine the number of months required to get Rs. 25.5 as simple interest on Rs. 850 at 3.6% per annum.

Accepted Answer

Option A: 10 months. SI = P * R * T / 100 => 25.5 = 850 * 3.6 * T / (100 * 12) (where T is in months). 25.5 = 8.5 * 3.6 * T / 12 => 25.5 = 2.55 * T => T = 10 months.

Question 42

Find the missing number in the following series: 10, 100, 200, 310, ?

Accepted Answer

Option A: 430. The pattern in the differences between consecutive terms is: 100 - 10 = +90; 200 - 100 = +100; 310 - 200 = +110. The next difference should be +120. Thus, 310 + 120 = 430.

Question 43

Find the missing letters in the following sequence in the correct order:

abca_bcaab_ca_bbc_a

Accepted Answer

Option B: abac. The sequence repeats an expanding group: 'abc' / 'aabc' / 'aabbc' / 'aabbcc' / 'a'. Filling in 'abac' at the blank positions completes this pattern: abca(a)bcaab(b)ca(a)bbc(c)a.

Question 44

If in a certain language PROSE is coded as PPOQE, how is LIGHT coded in that code?

Accepted Answer

Option C: LGGFT. 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.

Question 45

Introducing a woman, a man said, "Her husband is the only son of my father". How is that woman related to the man?

Accepted Answer

Option C: Wife. The 'only son of my father' for a man is the man himself. Therefore, the woman's husband is the man himself, meaning she is his wife.

Question 46

Find the odd one out from the given set of numbers.

14, 28, 35, 46, 56, 84

Accepted Answer

Option D: 46. All numbers in the set (14, 28, 35, 56, 84) are multiples of 7, except 46.

Question 47

Which group of letters is different from others?

Accepted Answer

Option D: TVWYZ. CBAED, IJHGK, and SRQPT each contain 5 consecutive letters of the alphabet rearranged. TVWYZ contains letters with gaps that are not consecutive (T, V, W, Y, Z - missing U and X).

Question 48

For the Assertion (A) and Reason (R) below, choose the correct alternative

Assertion (A): Simla is colder than Delhi.
Reason (R): Simla is at a higher altitude as compared to Delhi.

Accepted Answer

Option A: Both A and R are true and R is the correct explanation of A.. Both statements are true. As altitude increases, temperature decreases. Simla is colder than Delhi because it is at a higher altitude, making R the correct explanation of A.

Question 49

Accepted Answer

Option C: Aspect Ratio. The ratio of the width of a television screen to its height is called the aspect ratio. The traditional SDTV standard aspect ratio is 4:3.

Question 51

In T.V., the picture signal is

Accepted Answer

Option A: Amplitude modulated and at the low-frequency end of each channel allocation. In television broadcasting, the video (picture) signal is amplitude modulated (using VSB) and its carrier is positioned at the lower/low-frequency end of the channel bandwidth allocation.

Question 52

A PAM signal can be demodulated using

Accepted Answer

Option C: A Low pass filter. A Pulse Amplitude Modulated (PAM) signal contains the original message signal in its low-frequency envelope, which can be extracted by passing the PAM signal through a simple low pass filter.

Question 53

In time-division-multiplexing, each multiplexed signal occupies

Accepted Answer

Option B: The Entire Transmission Bandwidth. In Time Division Multiplexing (TDM), different signals are allocated different time slots. During its allocated time slot, each signal occupies the entire transmission bandwidth.

Question 54

What will be the upper sideband and lower sideband frequencies for amplitude modulation of a 5-kHz signal with 40-KHz carrier frequency?

Accepted Answer

Option B: 45 kHz and 35 kHz, respectively. Upper Sideband (USB) = fc + fm = 40 kHz + 5 kHz = 45 kHz. Lower Sideband (LSB) = fc - fm = 40 kHz - 5 kHz = 35 kHz.

Question 55

In FM to AM conversion, the input of the frequency-modulated signal converted into amplitude modulated signal by

Accepted Answer

Option A: Differentiator. An FM signal can be converted to an AM signal by passing it through a differentiator (or slope detector) whose frequency response changes frequency variations into amplitude variations.

Question 56

Pulse amplitude modulation is a process whereby

Accepted Answer

Option C: The height of a pulse is made proportional to the sampled value. Pulse Amplitude Modulation (PAM) is a modulation process where the amplitude (height) of the carrier pulses is made proportional to the amplitude of the sampled message signal.

Question 57

The amplitude modulation signal without a carrier is known as

Accepted Answer

Option B: DSB-SC. An amplitude modulated signal where the carrier is suppressed (removed) and both sidebands are transmitted is known as Double Sideband Suppressed Carrier (DSB-SC).

Question 58

Choose the incorrect statement about Switch Mode Power Supplies (SMPS):

Accepted Answer

Option C: SMPS has low input ripple. SMPS systems operate by high-frequency switching, which inherently generates high input and output ripple/noise. Thus, the statement that 'SMPS has low input ripple' is incorrect.

Question 59

The magnetic field produced in the stator of a three phase induction motor travels at

Accepted Answer

Option B: Synchronous speed. In a three-phase induction motor, the rotating magnetic field (RMF) generated in the stator travels at synchronous speed ($N_s = 120f/P$).

Question 60

Alternating Current (AC) cannot be measured by DC ammeter because

Accepted Answer

Option B: Average value of complete cycle is zero. A DC ammeter measures the average value of the current. Since a complete cycle of alternating current has equal positive and negative halves, its average value over a complete cycle is zero, resulting in no deflection.

Question 61

What is a common use of a Band Pass Filter in Radio Wave Propagation?

Accepted Answer

Option A: It allows only a specific range of frequencies to pass through. A Band Pass Filter is designed to allow signals within a specific range of frequencies (passband) to pass while attenuating/blocking frequencies outside this range.

Question 62

Classify the angle as acute, right, obtuse, straight:

List I: (a) 90°, (b) 45°, (c) 120°, (d) 180°
List II: (i) Acute, (ii) Right, (iii) Straight, (iv) Obtuse

Match I with II.

Accepted Answer

Option C: a-ii, b-i, c-iv, d-iii. Right angle = 90° (a-ii). Acute angle = 45° (b-i). Obtuse angle = 120° (c-iv). Straight angle = 180° (d-iii). This matches option C.

Question 63

Two statements are followed by four conclusions numbered in I, II, III, IV. You have to take the given statements to be true even if they seem to be at variance from commonly known facts, and then decide which of the given conclusions logically follows:

Statements:
1. All stars are planets.
2. All planets are trees.

Conclusions:
I. All planets are stars
II. All stars are trees
III. All trees are planets
IV. Some trees are stars

Accepted Answer

Option A: Only II and IV follow. Since all stars are planets and all planets are trees, we can conclude that all stars are trees (II). Also, since all stars are trees, some trees must be stars (IV). Conclusions I and III do not necessarily follow.

Question 64
