7 : 113 :: 11 : ? :: 15 : 481

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 265.

7 : 113 :: 11 : ? :: 15 : 481

The logic used here is:

7 : [7 × {(7 × 2) + 2}] + 1 = 113

15 : [15 × {(15 × 2) + 2}] + 1 = 481

Similarly, 

11 : [11 × {(11 × 2) + 2}] + 1 = 265
