Question
How many boxes are kept between V and the box which is
kept immediately below box U? Study the following information carefully and answer the question given below: Nine boxes viz. S, T, U, V, W, X, Y, Z and R are kept one above another but not in the same order. The box kept at the bottommost position is numbered as 1 and the box kept at the topmost position is numbered as 9. At most two boxes are kept below box U. Three boxes are kept between R and the box which is kept immediately above box U. W is kept two boxes above box R. Two boxes are kept between W and S. Box Z is kept immediately below box X. Box Y is kept three boxes below box X. Box T is kept above box V.Solution
We Have, At most two boxes are kept below box U. Three boxes are kept between R and the box which is kept immediately above box U.
Again we have, W is kept two boxes above box R. Two boxes are kept between W and S.
Case-III gets eliminated because no space left for W. Again we have, Box Z is kept immediately below box X. Box Y is kept three boxes below box X. Box T is kept above box V. Case-I gets eliminated because no space left for X and Y. So final arrangement is Case-2
