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 between D and E. Only F is kept above C. No box is kept below E. G is kept at some place below A but at some place above B.
How many boxes are kept below B?
The correct answer is
1
To solve this problem, let's organize the given information step by step.
- Understanding the basics: We have seven boxes: A, B, C, D, E, F, and G. These boxes are stacked on top of each other.
- Condition Analysis:
- Only two boxes are between D and E.
- No box is kept below E, which means E must be at the bottom.
- Only F is kept above C, meaning F is directly above C.
- G is somewhere below A but above B.
- Positioning the boxes:
- Since no box is below E, E must occupy the seventh position (from the top).
- This implies D occupies the fourth position, as it needs two boxes between itself and E.
- F is above C, so F and C are consecutive. If D is already in the fourth position, potential placements for F and C are constrained to:
- F is first, C is second or F is second, C is third.
- Now, for G being below A but above B, the only feasible placement is:
- A is in the first position, meaning B and G must be in the remaining positions out of the current state.
- Finally, the sequence needs to consider B in fifth (above E) and G in sixth (between B and E).
- This aligns G below A in position while leaving B in a position below G.
- Box stacking order: Hence, the complete order from top to bottom is:
- 1st: A
- 2nd: F
- 3rd: C
- 4th: D
- 5th: B
- 6th: G
- 7th: E
- Therefore, the answer to the question "How many boxes are kept below B?" is 1 box.
The correct answer is 1.

Important Questions from Puzzle (Notes)
- There are five men - A, B, C, D and E, six women P, Q, R, S, T and Z. A, B, and R are advocates. S, Q, P, D and C are doctors and the rest are teachers. A team has to be selected from these eleven persons subject to the following conditions:
(I) A, P and Z have to be together.
(II) B cannot go with D or R.
(III) E and Q have to be together.
(IV) C and T have to be together.
(V) D and P cannot go together.
(VI) C cannot go with Q.
If the team formed consists of two male advocates, two lady doctors and one teacher, the members of the team can be: - Seven boxes S, F, G, H, T and U are kept one over the other but not necessarily in the same order. Only two boxes are kept below S. Only one box is kept above U. Only one box is kept between U and B. G is kept immediately above F. T is kept at some place below H.
How many boxes are kept between H and G? - Seven boxes E, F, G, H, S, T and U are kept one over the other but not necessarily in themsame order. No box is kept above E. Only three boxes are kept between E and U. Only one box is kept between G and H. H is kept immediately above U. Only four boxes are kept between G and F. T is kept at some place above S. Which box is kept second below T?
- Seven boxes E, F, G, H, S, T and U are kept one over the other but not necessarily in the same order. H is kept immediately above E. T is kept immediately above U. Only F is kept above S. Only two boxes are kept above H. T is not kept at third position from the bottom.
How many boxes are kept between G and F? - Seven boxes E, F, G, H, S, T and U are kept one over the other but not necessarily in the same order. Only H is kept above E. Only T is kept between E and S. Only F is kept below U.
