Question

Seven boxes A, B, C, D, E, F and G are kept one over the other but not necessarily in the same order. Only two boxes are kept below G. Only one box is kept above B. Only one box is kept between B and D. A is kept immediately above C. E is kept at some place below F. Which box is kept at the top?

• A. B
• B. F
• C. D
• D. A

Answer 1

Answer:

B. F

Box F is kept at the top.

1. Positions of B, G, and D:

   • "Only one box is kept above B" means B is at position 6.

   • "Only two boxes are kept below G" means G is at position 3.

   • "Only one box is kept between B and D" means D must be at position 4 (since position 8 doesn't exist).

2. Positions of A and C:

   • "A is kept immediately above C." The only two consecutive open slots remaining are positions 2 and 1. Therefore, A is at position 2 and C is at position 1.

3. Positions of F and E:

   • The remaining slots are positions 7 and 5. Since "E is kept at some place below F," F must take the topmost slot at position 7, leaving E at position 5.

Final Stack Order (Top to Bottom):

• 7: F (Top)

• 6: B

• 5: E

• 4: D

• 3: G

• 2: A

• 1: C (Bottom)
