Five boxes P, Q, R, S, T are stacked one above the other. R is above S but below Q. T is at the bottom. P is just above T. Which box is at the top?
Step-by-step Solution:
Let's arrange the boxes step-by-step from bottom to top: 1. T is at the bottom. 2. P is just above T. (Stack so far: P, T) 3. R is above S but below Q. This means the relative order is Q > R > S. 4. Placing these three above P, the final stack from top to bottom is: Q, R, S, P, T. The box at the top is Q.
