Ten boxes are placed in a cupboard such that the bottom box is numbered 1, the box immediately above it is numbered 2, and so on, with the topmost box numbered 10. Four boxes are placed between J and K, and K is placed at an odd-numbered position. Box K is placed below box J. Box M is placed below box K. Two boxes are placed between K and L, and L is placed immediately below box Q. Box B is placed below box M. Box Q is placed at the 7th position. Box I is placed at an even-numbered position but above box P. Box A is placed immediately above box R. Which box is placed at the bottom?

J
K
I
इनमें से कोई नहीं

Correct answer: इनमें से कोई नहीं

Solution

With Q fixed at position 7, the clues force K, L, M, and B into lower positions and J into a higher one. None of J, K, or I can be placed at the bottom while satisfying all conditions, so the bottom box is not among the first three options.
