31. Select the option that is related to the fifth term in the same way as the second term is related to the first term and the fourth term is related to the third term. [S.S.C CHSL 09/06/2022 (Afternoon)]

7689 : 120 :: 6178 : 88 :: 3284 : ?

Correct Answer: (a) 68
Solution:The pattern followed here is :

(a : b) → sum of digit of a × 4 = b

(7689 : 120) → {(7 + 6 + 8 + 9) × 4} ⇒ 30 × 4 = 120

(6178 : 88) → {(6 + 1 + 7 + 8) × 4} ⇒ 22 × 4 = 88

Similarly,

(3284 : ?) → {(3 + 2 + 8 + 4) × 4} ⇒ 17 × 4 = 68

Hence, "68" is the correct answer.

32. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [S.S.C CHSL 09/06/2022 (Evening)]

9 : 32 :: 17 : 56 :: 15 : ?

Correct Answer: (c) 50
Solution:The pattern followed here is :

(a : b) → a × 3 + 5 = b

(9 : 32) → 9 × 3 + 5 = 32

(17 : 56) → 17 × 3 + 5 = 56

Similarly,

(15 : ?) → 15 × 3 + 5 = 50

Hence, "50" is the correct answer.

33. Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. [S.S.C CHSL 09/06/2022 (Evening)]

14 : 112 :: 24 : 312 :: 18 : ?

Correct Answer: (b) 180
Solution:The pattern followed here is :

(a : b) → {a × (a ÷ 2) + 1} = b

(14 : 112) → {14 × (14 ÷ 2) + 1} ⇒ 14 × 8 = 112

(24 : 312) → {24 × (24 ÷ 2) + 1} ⇒ 24 × 13 = 312

Similarly,

(18 : ?) → {18 × (18 ÷ 2) + 1} ⇒ 18 × 10 = 180

Hence, "162" is the correct answer.
