16: 50:: 49:? :: 144: 338
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 128.
The logic used here is:
16: 50
42 = 16
4 + 1 = 5
52 × 2 = 25 × 2 = 50
144: 338
122 = 144
12 + 1 = 13
132 × 2 = 169 × 2 = 338
Similarly,
49:?
72 = 49
7 + 1 = 8
82 × 2 = 64 × 2 = 128
Hence, option 1 is the correct answer.
