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. 24 : 4.
Logic: 2nd number × 6 + 1 = 1st number.
Except "24 : 4", All number pairs follow the same logic while 24 : 4 → 4 × 6 + 1 = 25 ≠ 24.
