Answer the questions based on the information given below. Six boxes R, S, T, U, V and W are kept one above another such that bottommost box is numbered as 1 and box above it is numbered as 2 and so on. R is two boxes above S. Only two boxes are between R and W. As many boxes are kept above S as below
V. At most two boxes are kept between T and U. T is not kept adjacent to
V. How many boxes are kept between U and W?

R is two boxes above S. Only two boxes are between R and W. As many boxes are kept above S as below V. There will be two cases: If R is kept at place no. 5, then S will be kept at place no. 3. W will be kept at place no. 2. As three boxes are above S, so V will be kept at place no. 4. If R is kept at place no. 4, then S will be kept at place no. 2. W will be kept at place no. 1. As four boxes are above S, so V will be kept at place no. 5. At most two boxes are kept between T and U. T is not kept adjacent to V. Case 1 will get discarded as we cannot place T and U. If T is kept at place no. 3, then U will be kept at place no. 6. Final arrangement as shown below:
