The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3:17.
The logic followed is:
Logic: First No.2 +2 = Second No.
Option (1) 19:363 → 192 + 2 =363
Option (2) 13: 171 → 132 + 2 = 171
Option (3) 3:17 → 32 + 2 = 11 ≠17
Option (4) 7:51 → 72 + 2 = 51
Thus, 3:17 is odd as it does not follow thre logic.
Hence, 3:17 is the correct answer.
