Three of the following four options are alike in a certain way and thus form a group. Which is the option that does NOT belong to that group?
(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).
- A.
2 – 4 – 8
- B.
2 – 2 – 4
- C.
3 – 2 – 5
- D.
1 – 3 – 3

Show answer & explanation
Correct answer: C
The correct answer is Option C (3 – 2 – 5). The underlying pattern in this question involves performing multiplication operations on the whole numbers provided. In three of the options, the third number is exactly the product of the first two numbers. For instance, in Option A (2 – 4 – 8), multiplying 2 by 4 yields 8. Similarly, in Option B (2 – 2 – 4), 2 multiplied by 2 equals 4, and in Option D (1 – 3 – 3), 1 multiplied by 3 results in 3. However, this relationship fails for Option C because multiplying the first two numbers (3 and 2) gives 6, not 5. Since Option C does not follow the established rule where the third number is the product of the first two, it is the odd one out and does not belong to the group.
