SSC CHSL 2015 PYQs

Question 1

4348414244?47??

Accepted Answer

The series has two alternating patterns: 43, 41, 44, 47... (subtract 2, add 3, add 3) and 48, 42, ?, ? (subtract 6, subtract 6). The missing numbers are 49, 45, 46.

Question 2

Hockey : India :: Baseball : ?

Accepted Answer

The analogy is based on a country and its national sport. Hockey is India's national sport, and Baseball is the national sport of the USA.

Question 3

Patient : Flower bed :: ?

Accepted Answer

A patient is kept in a 'bed'. Similarly, a 'baby' is kept in a 'cradle'. This establishes a 'kept in' relationship.

Question 4

If P denotes ÷, Q denotes X, R denotes + and S denotes -, then 16Q12P6R5S4= ?

Accepted Answer

Substitute the symbols and apply BODMAS: 16 × 12 ÷ 6 + 5 - 4. First division (12÷6=2), then multiplication (16×2=32), then addition (32+5=37), finally subtraction (37-4=33).

Question 5

54963?724652045

Accepted Answer

The pattern involves multiplying the digits of the previous number to get the next. 5*4=20, 9*6=54, 3*1=3, 7*2=14, 4*6=24, 5*2=10, 0*4=0, 5*0=0. So, the missing number is 1.

Question 6

Ant : Fly : Bee :: Hamster : Squirrel: ?

Accepted Answer

The first set (Ant, Fly, Bee) are all insects. The second set (Hamster, Squirrel) are both rodents. Therefore, the missing word must also be a rodent, which is Mouse.

Question 7

VVXY : RRTU :: FFHI : ?

Accepted Answer

The pattern is a decrease of 4 positions for the first two letters (V-4=R) and a decrease of 3 positions for the last two letters (X-3=U, Y-3=T). Applying this to FFHI gives SSUV.

Question 8

If FADE is coded as 3854 then how can GAGE be coded ?

Accepted Answer

Each letter is coded by its position in the alphabet minus 3. F(6)-3=3, A(1)+7=8, D(4)+1=5, E(5)-1=4. Applying this pattern to GAGE: G(7)-3=4, A(1)+7=8, G(7)-3=4, E(5)-1=4. So, GAGE is 4844.

Question 9

144 : 13 :: 49 ?

Accepted Answer

The pattern is (square root of first number) + 1. So, for 144, it's sqrt(144) + 1 = 12 + 1 = 13. For 49, it's sqrt(49) + 1 = 7 + 1 = 8.

Question 10

QPOR : XWVY : LKJM : ?

Accepted Answer

The pattern involves reversing the first two letters and the last two letters, then shifting them. QPOR becomes QP and OR. XWVY becomes XW and VY. LKJM becomes LK and JM. Applying this, SRQT is the correct answer.

Question 11

The sum of ages of mother, daughter and son is 87 years. What will be the sum of their ages after 8 years ?

Accepted Answer

Each of the three individuals will age by 8 years. So, the total increase in their combined age will be 3 * 8 = 24 years. Add this to the current sum: 87 + 24 = 111 years.

Question 12

Find the odd number.

Accepted Answer

All numbers except 56 are powers of 2 (2^1, 2^7, 2^4 respectively). 56 is not a power of 2, making it the odd one out.

Question 13

ABDE GHJK MNPQ

Accepted Answer

The pattern is +2 letters, skip 1, +2 letters, skip 1. ABDE skips C, GHJK skips I, MNPQ skips O. Following this, STVW skips U.

Question 14

If SUNDAY = 18, MONSOON = 21, YEAR = 12, then THURSDAY = ?

Accepted Answer

The pattern is: (Number of letters in the word) × 3. SUNDAY has 6 letters, 6x3=18. MONSOON has 7 letters, 7x3=21. YEAR has 4 letters, 4x3=12. THURSDAY has 8 letters, so 8x3=24.

Question 15

ACE : GIK :: MOQ : ?

Accepted Answer

The pattern is +6 for each letter's position. A(1)+6=G(7), C(3)+6=I(9), E(5)+6=K(11). Applying this to MOQ: M(13)+6=S(19), O(15)+6=U(21), Q(17)+6=W(23). So, SUW.

Question 16

After going 80 m from his house towards east, a person turns  left and goes 20 m, then turns right and moves 100 m, then turns left and goes 60 m, then turns right and goes 120 m to reach the park. What is the distance between his house and the park ?

Accepted Answer

Calculate net displacement in East-West and North-South directions. East: 80+100+120 = 300m. North: 20+60 = 80m. Use Pythagoras theorem: sqrt(300^2 + 80^2) = sqrt(90000 + 6400) = sqrt(96400) = 310.48m. The options provided are incorrect, assuming the correct answer is 310.48m, which is not among the options.

Question 17

GNIDAER : READING :: NOITULOS :?

Accepted Answer

The first word 'GNIDAER' is the reverse spelling of 'READING'. Applying the same logic, 'NOITULOS' when reversed spells 'SOLUTION'.

Question 18

Unscramble the following letters to frame a meaningful word.  Then find out the correct numerical positions of the letters.O T Y S R H I1 2 3 4 5 6 7

Accepted Answer

The jumbled letters O T Y S R H I form the meaningful word 'HISTORY'. Mapping the original positions: H(6), I(7), S(4), T(2), O(1), R(5), Y(3). So the sequence is 6742153.

Question 19

Book : Wallet :: Cell

Accepted Answer

A book is made of pages, and a wallet is made of cells. Similarly, a cell is a fundamental unit that forms tissue. Thus, Tissue is the correct answer.

Question 20

If it is possible to form a word with the first, fourth, seventh and  eleventh letters in the word ‘SUPERFLUOUS’ write the first letter of that word.

Accepted Answer

Extracting the 1st, 4th, 7th, and 11th letters from 'SUPERFLUOUS' gives S, E, O, L. Rearranging these letters forms the word 'LOSE'. The first letter of 'LOSE' is L.
