Question : Directions: Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? (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.)
Option 1: (7 – 56)

Correct Answer: (6 – 48)
Solution : Let's check the given options – First option: (7 – 56); (7)2 + 7 = 49 + 7 = 56 Second option: (9 – 90); (9)2 + 9 = 81 + 9 = 90 Third option: (4 – 20); (4)2 + 4 = 16 + 4 = 20 Fourth option: (6 – 48); (6)2 + 6 = 36 + 6 = 42 ≠ 48
So, the fourth option is different from the other three options as the second number should be 42 instead of 48. Hence, the fourth option is correct.
