Seven boxes A, B, C, D, R, S, and T are kept one over the other but not necessarily in the same order. Only three boxes are kept below B. Only two boxes are kept between B and S. Only A is kept above C. R is kept at some place below D and at some place above T. Which box is kept at the second position from the bottom?

Correct option is B

T is in the second position from the bottom. From the clue "only three boxes are below B", B must be in the 4th position from the bottom. Since two boxes are between B and S, S must be either 1st or 7th. Trying S at the 1st position fits all remaining clues. The clue "only A is above C" places A at the top and C just below it. Now, R must be below D and above T. The arrangement that satisfies all conditions is: 1st–S, 2nd–T, 3rd–R, 4th–B, 5th–D, 6th–C, 7th–A. Hence, T is at the second position from the bottom.
· (a) D: ✘ D is in the 5th position from bottom.
· (b) T: ✔ Correct; T is exactly at the 2nd position.
· (c) C: ✘ C is at the 6th position.
· (d) A: ✘ A is at the top (7th position).
