SSC CGL (Prelims) Reasoning: Odd One Out questions with solutions

Q1. Three of the following four options are alike in a certain way and thus form a group. Which option does NOT belong to that group?

1. 2-4-8
2. 2-2-4
3. 3-2-5
4. 1-3-3

Answer: 3-2-5

In three options, the numbers follow a simple relation where the third number is derived from the first two in a consistent pattern. The set 3-2-5 does not match the same relation as the other three. Therefore, it is the odd one out.
