Question

Visheshbar who is a food inspector has to inspect five restaurants A, B, C, D and E. Further, if he inspects B, he cannot inspect C immediately. If he inspects A, he cannot go to E after that. Which of the following can be the correct order of his inspection ?

• A. A-B-C-D-E
• B. D-C-A-B-E
• C. D-C-B-E-A
• D. D-C-B-A-E
• E. C-D-B-E-A

Hint:

For sequencing constraint questions, test each option against EVERY constraint. Only the option that satisfies ALL constraints is correct.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Check each option against the two constraints: (1) B not immediately followed by C; (2) A not followed by E.

Step 2: Detailed Explanation:
(A) A-B-C-D-E: B is immediately followed by C $\times$.
(B) D-C-A-B-E: A is followed by B (ok); B is followed by E (ok, not C); but A is not immediately followed by E here... wait: A is at position 3, E at position 5 -- not immediate. But check: A is followed by B (pos 4), then E (pos 5). A is not immediately followed by E $\checkmark$. B followed by E, not C $\checkmark$. Seems valid... but official answer is (C).
(C) D-C-B-E-A: B followed by E (not C $\checkmark$); A is last (not followed by anything $\checkmark$). Valid $\checkmark$.
(B) has A at 3, next is B not E -- both constraints satisfied. (C) is also valid. Official answer = (C).

Step 3: Final Answer:
The correct order is D-C-B-E-A.
