Seven people T, U, V, W, X, Y & Z are standing in a single line facing a milk-booth. X is somewhere ahead of Y. There is exactly one person standing between V and Z. W is immediately behind T. Y is behind both U & W. If W & V are fourth and fifth in line respectively, then which of the following must be true?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Y is sixth
First in line is the person nearest the milk booth; “behind” means farther from the booth.
W is 4th and V is 5th (given). W is immediately behind T, so T is 3rd.
One person stands between V and Z, so Z is 3rd or 7th; 3rd is T’s, so Z is 7th.
Y is behind W, so Y is 5th, 6th or 7th; 5th and 7th are taken, so Y is 6th.
U and X take 1st and 2nd in either order, so only Y’s place is certain.
