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: 13 – 144
Option 2: 9 – 63
Option 3: 8 – 48
Option 4: 11 – 99

Correct Answer: 13 – 144
Solution : Let's check the options – First option: 13 – 144→13 × (13 – 2) = 13 × 11 = 143 ≠ 144 Second option: 9 – 63→9 × (9 – 2) = 9 × 7 = 63 Third option: 8 – 48→8 × (8 – 2) = 8 × 6 = 48 Fourth option: 11 – 99→11 × (11 – 2) = 11 × 9 = 99
So, only the first option does not follow the logic of the other three options. Hence, the first option is correct.
