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 on 13 such as adding /subtracting /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)

Correct Answer: 11 – 39
Solution :
Let's check each option –
First option:
15 – 56; 15 × 4 = 60 and 60 – 4 = 56
Second option:
13 – 48; 13 × 4 = 52 and 52 – 4 = 48
Third option:
11 – 39; 11 × 4 = 44 and 44 – 4 = 40 ≠ 39
Fourth option:
17 – 64; 17 × 4 = 68 and 68 – 4 = 64
So, only the third option doesn't follow the same pattern as followed by the given set of numbers. Hence, the third option is correct.
