Question

Seven executives P,Q,R,S,T,U and W reach office in a particular sequence.U reaches immediately before P but
does not immediately follow S. R is the last one to reach office T follows immediately after P and is subsequently
followed by W. Who ranks fourth in the sequence of reaching office?
(1) W
(2) U
(3) T
(4) None of these​

Answer 1

Clearly, U is followed by P; P by T; T by W.

Now, U does not immediately follow S and R reaches last.

Then the order of reaching office is : S, Q, U, P, T, W, R.

So, S is the first to reach office.

Hence, S is the answer.
