16 : 69 :: 24 : ? :: 31 : 144
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 109.
The logic used here is:
16 : 69
16 × 5 = 80
80 - 11 = 69
31 : 144
31 × 5 = 155
155 - 11 = 144
Similarly,
24 : ?
24 × 5 = 120
120 - 11 = 109
Hence, 109 is the correct answer.
