1If in a certain code TIGER is written as UJHFS, how is LION written in the same code?
A.MJPO
B.MKPO
C.NJPO
D.MJOP
Explanation: Each letter is shifted forward by one position in the alphabet (T->U, I->J, G->H, E->F, R->S). Applying the same +1 shift to LION gives M, J, P, O = MJPO.
2A series reads 3, 6, 11, 18, 27, ... What is the next term?
A.36
B.38
C.40
D.42
Explanation: The differences between consecutive terms are 3, 5, 7, 9 — increasing odd numbers. The next difference is 11, so 27 + 11 = 38.
3Pointing to a photograph, a man said, 'She is the daughter of my grandfather's only son.' How is the woman in the photograph related to the man?
A.Sister
B.Mother
C.Aunt
D.Cousin
Explanation: The grandfather's only son is the man's own father. The daughter of the man's father is therefore the man's sister.
4A train 150 metres long is running at 72 km/h. How long will it take to cross a platform 250 metres long?
A.15 seconds
B.18 seconds
C.20 seconds
D.25 seconds
Explanation: Speed = 72 km/h = 72 x 5/18 = 20 m/s. Total distance to cross the platform = train length + platform length = 150 + 250 = 400 m. Time = 400 / 20 = 20 seconds.
5The average of five consecutive even numbers is 30. What is the largest of these numbers?
A.32
B.34
C.36
D.38
Explanation: For consecutive numbers the average equals the middle term, so the middle number is 30. The five even numbers are 26, 28, 30, 32, 34, making 34 the largest.
6If 20% of a number is 50, what is 35% of the same number?
A.75.5
B.82.5
C.87.5
D.92.5
Explanation: If 20% = 50, then the number = 50 / 0.20 = 250. Therefore 35% of 250 = 0.35 x 250 = 87.5.
7A sum of money doubles itself in 8 years at simple interest. In how many years will it become four times?
A.16 years
B.20 years
C.24 years
D.32 years
Explanation: Doubling in 8 years means the interest earned equals the principal in 8 years, so the rate is 12.5% per year. To become four times, interest must equal three times the principal, requiring 3 x 8 = 24 years.
8In a row of 40 students, Ravi is 11th from the left end. What is his position from the right end?
A.29th
B.30th
C.31st
D.28th
Explanation: Position from the right = total students - position from left + 1 = 40 - 11 + 1 = 30. Ravi is 30th from the right end.
9Two pipes A and B can fill a tank in 12 hours and 18 hours respectively. If both are opened together, how long will they take to fill the tank?
A.6.5 hours
B.7.2 hours
C.7.5 hours
D.8 hours
Explanation: A fills 1/12 per hour and B fills 1/18 per hour. Combined rate = 1/12 + 1/18 = 3/36 + 2/36 = 5/36 per hour. Time = 36/5 = 7.2 hours.
10Find the odd one out: 8, 27, 64, 100, 125
A.27
B.64
C.100
D.125
Explanation: The numbers 8, 27, 64, 125 are perfect cubes (2^3, 3^3, 4^3, 5^3). 100 is a perfect square (10^2) but not a perfect cube, so it is the odd one out.

UPSC CAPF AC Study Tips from Top Performers

1Prioritise general mental ability — reasoning and quantitative aptitude form the largest scoring block of Paper I and reward consistent timed practice.
2Practise under negative marking: skip questions you cannot reasonably reason out, since each wrong answer costs one-third of the marks.
3Build a daily current-affairs habit covering national and international events, government schemes, sports, defence and the economy.
4Revise NCERT-level science, history, geography and polity first, then layer on standard reference books for depth.
5Solve previous years' Paper I papers to learn the UPSC question style and calibrate your speed for 125 questions in 2 hours.
6Track accuracy, not just attempts — aim to raise the ratio of correct answers to total attempts to offset the negative-marking penalty.
7Begin physical fitness preparation early, since the PST/PET and medical examination are qualifying stages later in the process.
