SSC CHSL 2015 PYQs

Question 1

Velocity : Speed : : Veracity :?

Accepted Answer

Velocity and Speed are synonyms. Similarly, Veracity means truthfulness. Therefore, Truth is the correct synonym for Veracity.

Question 2

The mall is 250 meters north-west of the market. The school is 250 meters south-west of the market. In which direction is the school from the mall ?

Accepted Answer

Draw a diagram. Market is the common point. Mall is NW of Market, School is SW of Market. From Mall, School is directly South.

Question 3

Blacksmith : Hammer : : ?

Accepted Answer

A blacksmith uses a hammer as a tool. Similarly, a surgeon uses forceps as a tool for operations. This establishes an 'agent-tool' relationship.

Question 4

Iodine : Goitre : : ?

Accepted Answer

Lack of Iodine causes Goitre. Similarly, lack of Insulin causes Diabetes. This establishes a deficiency-disease relationship.

Question 5

SUMO : PRJL : : TAXI : ?

Accepted Answer

The pattern is -3, -3, -3, -3 for each letter. S-3=P, U-3=R, M-3=J, O-3=L. Applying this to TAXI: T-3=Q, A-3=X, X-3=U, I-3=F. So, TAXI becomes QXUF.

Question 6

CAT : DDY : : BIG : ?

Accepted Answer

The pattern is +1, +1, +1 for the first letter, +1, +1, +1 for the second, and +1, +1, +1 for the third. C(+1) = D, A(+3) = D, T(+5) = Y. Applying this to BIG: B(+1)=C, I(+3)=L, G(+5)=L. So, BIG : CLL.

Question 7

Doctor : Medicine : : 2 : Judgement

Accepted Answer

A doctor provides medicine. Similarly, a judge provides judgement. The analogy is based on a professional and their primary output/service.

Question 8

16, 30, ?, 79, 114

Accepted Answer

The differences between consecutive numbers are +14, +21, +28, +35. The pattern is an arithmetic progression of differences (7, 7, 7). So, 30 + 21 = 51.

Question 9

Concord : Agreement :: Discord : ?

Accepted Answer

Concord is a synonym for Agreement. Similarly, Discord is a synonym for Conflict. The relationship is one of synonyms.

Question 10

EAGLE : FCJPJ : : CRAWL : ?

Accepted Answer

The pattern is +1, +2, +3, +4, +5 for each letter. Applying this to CRAWL: C+1=D, R+2=T, A+3=D, W+4=A, L+5=Q. So, CRAWL becomes DTDAQ.

Question 11

134 : ACD : : 567 : ?

Accepted Answer

The pattern maps numbers to their corresponding alphabet positions (A=1, B=2, C=3, D=4). So, 134 becomes ACD. Applying this, 567 maps to EFG.

Question 12

1, 48, 4, 24, 7, ? 10, 2

Accepted Answer

This is an alternating series. The first series (1, 4, 7, 10) increases by 3. The second series (48, 24, ?, 2) divides by a consecutively increasing number: 48/2=24, 24/3=8, 8/4=2.

Question 13

Female : Feminine : : Male : ?

Accepted Answer

The analogy is between a noun and its corresponding adjective. 'Feminine' describes 'Female'. Similarly, 'Masculine' describes 'Male'.

Question 14

OTE, PUF, QVG, RWH, ?

Accepted Answer

Each letter in the series advances by one position. O+1=P, P+1=Q, Q+1=R, so R+1=S. T+1=U, U+1=V, V+1=W, so W+1=X. E+1=F, F+1=G, G+1=H, so H+1=I. Thus, the next term is SXI.

Question 15

42 : 20 :: 64 : ?

Accepted Answer

The pattern is (Number / 2) - 1. So, for 42, it's (42 / 2) - 1 = 21 - 1 = 20. Applying this to 64, we get (64 / 2) - 1 = 32 - 1 = 31.

Question 16

ADFM : CFHO : : CFHO : ?

Accepted Answer

The pattern is +2, +2, +2, +2 for each letter. A+2=C, D+2=F, F+2=H, M+2=O. Applying this to CFHO: C+2=E, F+2=H, H+2=J, O+2=Q. So the answer is EHJQ.

Question 17

4, __ , 19, 39, 79, 159

Accepted Answer

The pattern is (previous number * 2) + 1. Applying this, 4 * 2 + 1 = 9. Then 9 * 2 + 1 = 19, and so on. Thus, 9 is the missing number.

Question 18

16, 61, 25, 52, 36, 63, 49, ?

Accepted Answer

The pattern involves a number followed by its digits reversed. So, 16 is followed by 61, 25 by 52, 36 by 63. Following this, 49 should be followed by 94.

Question 19

PS : VY : : FI : ?

Accepted Answer

The pattern is +3, +3. P (+3) = S, V (+3) = Y. Similarly, F (+3) = I, so I (+3) = L. Thus, the missing pair is LO.

Question 20

4863 - 2436 : : 8132 - 4261 ::

Accepted Answer

The pattern is that the second number is approximately half of the first number. 2436 is about half of 4863, and 4261 is about half of 8132. Option 2 follows this pattern.
