The same operation(s) are followed in all the given number pairs except one. Find that odd number pair.
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 12 : 152.
Logic: 1st number × 13 = 2nd number
Except for 12 : 152, all number pairs follow the same logic. While 12 : 152 → 12 × 13 = 156 ≠ 152
