Seven people A, B, C, D, E, F and G are sitting around a circular table, facing the center (but not necessarily in the same order). F is sitting fourth to the right of D. E is sitting second to the left of F. B is sitting to the immediate left of G. A is not an immediate neighbour of F. How many people are sitting between C and D when counted from the right of D?

ATwo

BOne

CFour

DThree

Answer:

A. Two

Read Explanation:

Fix a reference

In circular arrangements, fix one person. Let D be fixed.

Place F

“F is fourth to the right of D”
(7 people ⇒ 4th right = 3rd left)

So F is placed opposite side relative to D.

Place E

“E is second to the left of F”

Place B and G

“B is immediate left of G”

Use condition

“A is not an immediate neighbour of F”

Arrange remaining positions accordingly.


After placing all consistently, we get a valid arrangement.

Final check:

Count people between C and D from the right of D

The count comes out to 2 people

Final Answer: 2
