Question

Two sets of numbers are given below. In each set, the second number is obtained by performing certain mathematical operations on the first number. Similarly, by performing certain mathematical operations on the second number, the third number is obtained and this pattern continues in the same way. Which of the following options follows these numbers?
(Note: Mathematical operations should be performed on the whole number without separating the numbers into their components.)
108 – 54 – 27 – 25
68 – 34 – 17 – 15

A.

28 – 14 – 7 – 9

B.

80 – 40 – 20 – 10

C.

88 – 44 – 22 – 20

D.

54 – 27 – 9 – 7

Correct option is C

Given:
108 – 54 – 27 – 25
68 – 34 – 17 – 15
Logic: 1st number ÷\div 2 = 2nd number , 2nd number ÷\div 2 = 3rd number, 3rd number - 2 = 4th number
1st pair: 108 – 54 – 27 – 25
108 ÷ 2 = 54, 54 ÷ 2 = 27, 27 - 2 = 25
2nd pair: 68 – 34 – 17 – 15
68 ÷ 2 = 34, 34 ÷ 2 = 17, 17 - 2 = 15
Lets check by options follow this logic;
Option (a); 28 – 14 – 7 – 9 (Not follow)
28 ÷ 2 = 14, 14 ÷ 2 = 7, 7 + 2= 9
Option (b); 80 – 40 – 20 – 10 (Not follow)
80 ÷ 2 = 40, 40 ÷ 2 = 20, 20 - 10 = 10 
Option (c); 88 – 44 – 22 – 20 (Follow)
88 ÷ 2 = 44, 44 ÷ 2 = 22, 22 - 2 = 20
Option (d); 54 – 27 – 9 – 7 (Not follow)
54 ÷ 2 = 27, 27 ÷ 3 = 9, 9 - 2 = 7
Thus, the correct answer is (c).
