Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule/Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations can be performed on 13, such as adding /subtracting /multiplying, etc., to 13. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: 12 – 50
Solution :
Let's check the options –
First option:
12 – 50; 12 × 4 = 48; 48 + 4 = 52 ≠ 52
Second option:
8 – 36; 8 × 4 = 32; 32 + 4 = 36
Third option:
10 – 44; 10 × 4 = 40; 40 + 4 = 44
Fourth option:
18 – 76; 18 × 4 = 72; 72 + 4 = 76
So, only the first option does not follow the same logic as followed by the other three options. Hence, the first option is correct.
