A, B, C, D and E are standing in a row. D is the immediate neighbour of A and E. B is at the right of E and C is in the extreme right. Who is fourth to the left of C?
- AB
- BE
- CC
- DA
Solution & Step-by-step Explanation
Let's determine the positions from left to right:
C is at the extreme right end: …,…,…,…,C
B is to the right of E, and since C is at the extreme right, the arrangement towards the end must be E,B,C.
D is the immediate neighbour of both A and E, which means D must sit exactly between them (A,D,E).
Combining these gives the full linear layout from left to right: A,D,E,B,C.
Counting to the left from C:
1st left: B
2nd left: E
3rd left: D
4th left: A
Thus, A is fourth to the left of C.
C is at the extreme right end: …,…,…,…,C
B is to the right of E, and since C is at the extreme right, the arrangement towards the end must be E,B,C.
D is the immediate neighbour of both A and E, which means D must sit exactly between them (A,D,E).
Combining these gives the full linear layout from left to right: A,D,E,B,C.
Counting to the left from C:
1st left: B
2nd left: E
3rd left: D
4th left: A
Thus, A is fourth to the left of C.
