Answer 1

Step-by-step explanation:

First of all, V is at the west end. So we must keep V first.

:

U is neighbour of T and X is of W.

And as S is fourth to the right of W, there are 3 people between them.

So, we can put the between arrangement as :

WXUTS

OR

WXTUS

Joining them, the possible arrangements are :

1) VWXUTSYZ

2) VYZWXUTS

3) VYWXUTSZ

4) VZWXUTSY

5) VYZWXTUS
