Seven boxes, A, B, C, D, E, F and G, are kept one over the other, but not necessarily in the same order. G is kept third from the bottom. Only two boxes are kept between G and C. Only F is kept below B. E is kept immediately below A. Which box is fourth from the top?
E
Number the positions 1 (bottom) to 7 (top). G is third from the bottom, so G is at position 3.
Only two boxes are kept between G and C, so C is either at position 6 (above G) or position 0 (below G). Since position 0 does not exist, C is at position 6.
“Only F is kept below B” means exactly one box lies below B, so B is at position 2 and F is at position 1.
Remaining positions 4, 5 and 7 are to be filled by A, D and E, with E immediately below A. The only valid placement is A at 5 and E at 4, leaving D at position 7.
Final order from top: 7-D, 6-C, 5-A, 4-E, 3-G, 2-B, 1-F.
The fourth box from the top is at position 4, which is E.
Hence, the box fourth from the top is E.
Seven boxes B, C, D, E, Q, R and S are kept one over the other but not necessarily in the same order. No box is kept below C. Only two boxes are kept between E and C. Only Q is kept above D. S is kept at some place below B but at some place above R. Which box is kept immediately above S?
Seven boxes, G, H, I, L, M, N and O, are kept one over the other, but not necessarily in the same order.
No box is kept above M. Only two boxes are kept between L and H. Only three boxes are kept between M and H. N is kept immediately above H. Only four boxes are kept between L and I. G is kept at some place above O. Which box is kept second above G?
Seven boxes M, N, O, P, X, Y and Z are kept one over the other but not necessarily in the same order. Only N is kept above P. Only two boxes are kept between P and X. Only O is kept below Y. Z is not kept immediately above X. Which box is kept second above M?
Seven boxes F, A, C, T, O, R and S are kept one over the other but not necessarily in the same order. Only two boxes are kept below A. Only three boxes are kept between T and A. Only one box is kept between S and R. R is kept immediately above A. Only four boxes are kept between S and F. O is kept at someplace above C. How many boxes are kept below O?
Seven boxes I, J, K, M, N, P and Q are kept one over the other but not necessarily in the same order. Only three boxes are kept between box K and box P. Only one box is kept between box I and box P, where box I is kept at the topmost position. Box N is kept immediately above box Q. Only two boxes are kept between box N and box M. Which box is kept fourth from the top?
