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: A
Explanation
The correct answer is option 1 i.e. 24 : 4.
1. 24 : 4 → 4 + 4 ÷ 2 = 4 + 2 = 6 ≠ 24
2. 36 : 24 → 24 + 24 ÷ 2 = 24 + 12 = 36
3. 12 : 8 → 8 + 8 ÷ 2 = 8 + 4 = 12
4. 72 : 48 → 48 + 48 ÷ 2 = 48 + 24 = 72
