Q1:jipmat 2025LRDI › ArrangementsMediumLR · MCQ
Seven persons A, B, C, D, E, F and G are sitting around a circle and are facing the centre. G is second to the left of C, who is to the immediate left of F. A is third to the left of E. B is between D and E. Who is sitting immediate right of G?
- AC
- BD
- CF
- DA
Pick an option to attempt
Step 1: Anchor the primary cluster
Since they are facing the center, 'Left' implies clockwise and 'Right' implies counter-clockwise. Let's arbitrarily place F at Position 1.
* 'C ... is to the immediate left of F' C is at Position 2 (clockwise).
* 'G is second to the left of C' G is at Position 4.
* Current circle (Positions 1 through 7): F, C, _ , G, _ , _ , _ .
Step 2: Place the secondary cluster
We know 'B is between D and E', meaning D-B-E or E-B-D will monopolize three consecutive seats. The only open block of three is Positions 5, 6, and 7.
We also know 'A is third to the left of E'. Let's test E's possible spots:
* If E is at 5, third to the left (clockwise) is 1 (F's occupied seat). Invalid.
* If E is at 6, third to the left is 2 (C's occupied seat). Invalid.
* If E is at 7, third to the left is 3. This seat is perfectly empty!
So, E locks into Position 7, and A takes Position 3.
Since B is squeezed between D and E, B must sit at 6, forcing D into 5.
Step 3: Secure the target
The final clockwise arrangement is locked: F, C, A, G, D, B, E.
The question asks who is sitting to the immediate right (counter-clockwise) of G. G is at Position 4; one spot counter-clockwise is Position 3, which is occupied by A.
Final Answer: A
