Seven boys B1, B2, B3, B4, B5, B6 and B7 are sitting around a circular table, facing towards the centre (not necessarily in the
same order). B3 is second to the left of B6. B1 is third to the left of B3. B7 is third to the left of B6.
B4 is not the immediate neighbour of B6. B2 is not the immediate neighbour of B1, B5 is the immediate neighbour of B1 and
B6.. Three out of the following four options are similar by a certain logic and form a group. Which of the following does NOT
belong to that group?

Correct AnswerExplanation:
Alright, let’s break down what we know:
- Seven boys: B1, B2, B3, B4, B5, B6, B7
- All are sitting around a circular table facing the centre.
- B3 is second to the left of B6.
- B1 is third to the left of B3.
- B7 is third to the left of B6.
- B4 is not next to B6.
- B2 is not next to B1.
- B5 is next to both B1 and B6.
Let’s look quickly at the logic:
- Options 1, 2, and 3 all have trios where, in the arrangement, all three can (or do) sit next to each other.
- Option 4 has B7, B4, B1. This group doesn't form a direct logical link—at least one of these isn't directly linked to the other two, based on the positions and constraints.
- The odd one out is the set that doesn’t make a neat “connected” group based on the rules.
Here’s the thing:
Option 4: B7, B4, B1—does not fit the grouping logic of the other three, because these don’t sit together or aren’t connected via the seating rules given.
So — Option: 4 (B7, B4, B1) is the odd one out.
