407 : 37 :: ? : 59 :: 253 : 23
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 649.
The logic used here is:
407 : 37
37 × 9 = 333
333 + (37 × 2) = 333 + 74 = 407
253 : 23
23 × 9 = 207
207 + (23 × 2) = 207 + 46 = 253
Similarly,
? : 59
59 × 9 = 531
531 + (59 × 2) = 531 + 118 = 649
Hence, 649 is the correct answer.
