Correct Answer : B

The attendance on the fifth day is 40.

Convert each average into a total:

\[ \begin{aligned} \text{first 4 days} &= 4 \times 30 = 120 \\ \text{first 5 days} &= 5 \times 32 = 160 \\ \text{fifth day} &= 160 - 120 = 40 \end{aligned} \]

Shortcut: the fifth day must lift the average of five days by 2, so it is the old average plus \(5 \times 2\): \(30 + 10 = 40\). 32 is the new average itself, a common slip, and 36 and 38 do not give a five-day total of 160.

Correct Answer : C

The duration of service was 31 years 2 months and 19 days.

From 13 January 1992 to 13 January 2023 is 31 years, and on to 13 March 2023 is 2 more months. From 13 March to 31 March is 18 days, and counting both the joining day and the retirement day as days of service adds one more, giving 19 days.

The options with 30 years miscount the years. 31 years 2 months and 18 days is the difference between the dates without counting the joining day, while the key counts both ends of the service.

Correct Answer : C

The new average weight is 67.675 kg. The total weight of the 35 students is 35 x 66 = 2310 kg. When six students of average 58.5 kg leave, 351 kg goes out, and when eleven students of average 68 kg join, 748 kg comes in. The class then has 35 - 6 + 11 = 40 students.

\[ \text{Total} = 2310 - 351 + 748 = 2707 \text{ kg} \]

\[ \text{Average} = \frac{2707}{40} = 67.675 \text{ kg} \]

The options 66.375, 66.5 and 68.5 do not equal 2707 divided by 40, so the third option is the answer. As a check, 40 students at 67.675 kg each weigh 2707 kg, which is the total found above.

Correct Answer : A

The remaining food was supposed to last for 500 men for 27-3 = 24 days. Total remaining food = \(500 \times 24\) man-days. Now, the number of men is \(500+300=800\). The food will last for \((500 \times 24) / 800 = 12000 / 800 = 15\) days.

Correct Answer : B

The hourly distances form an arithmetic progression: 30, 32, 34, … with \( a = 30 \), \( d = 2 \) and \( n = 10 \).

\[ S_{n} = \frac{n}{2}\left[2a + (n-1)d\right] \]

\[ = \frac{10}{2}\left[60 + 9 \times 2\right] = 5 \times 78 = 390 \text{ km} \]

Multiplying the first hour's 30 km by 10 would give 300 km, ignoring the acceleration entirely.

Correct answer: A is true but R is false.

Pluto is indeed the coldest of the bodies traditionally counted as planets, at around \( -230^{\circ}\mathrm{C} \), so A is true. But the cause is its enormous distance from the sun - sunlight there is some 1600 times fainter than at the earth - not the slant of the rays, which is what makes the earth’s poles cold. R is false.

Correct Answer : D

E is C's Wife.

A is B's brother and A and D are brothers, so A, B and D are siblings. E is B's mother, so she is the mother of all three; C is D's father, so he is the father of all three. The mother and father of the same children are husband and wife.

Niece, sister and aunt would each place E outside the parent generation, which the facts rule out.

Drawing a quick family tree, with C and E above A, B and D, makes the relation obvious.

The blanks are filled by G and P, so the answer is GP.

Take the first letters: A, B, D, _, K, P. They move forward by 1, 2, 3, 4 and 5 places (A to B is +1, B to D is +2, D to G is +3, G to K is +4, K to P is +5), so the first blank is G. Take the second letters: Z, Y, W, T, _, K. They move back by 1, 2, 3, 4 and 5 places (Z to Y, Y to W, W to T, T to P, P to K), so the second blank is P.

The other options, HP, GO and HQ, each fail at least one of the two letter patterns.

The most populous district in the 2011 census was Thane.

Thane district in Maharashtra had a population of about 1.1 crore (11 million) in 2011, the highest of any district in India. It was later split, with Palghar carved out in 2014.

Lucknow is a large city but its district had far fewer people. Jaisalmer and Kachchh are the largest districts by area in Rajasthan and Gujarat, and among the most thinly populated, which makes them distractors on size rather than population.

The correct matching is A-2, B-1, C-3.

Leprosy is caused by the bacterium Mycobacterium leprae. Rabies is caused by a virus (a lyssavirus) passed on by the bite of an infected animal. Malaria is caused by the protozoan Plasmodium, carried by the female Anopheles mosquito.

The option A-1, B-2, C-3 swaps leprosy and rabies, making rabies bacterial. The other two put malaria with bacteria or viruses, which is the one pairing most candidates know well.
