Previous Year Question (PYQs)
Four people (P,Q,R & S) are standing in a queue. Q is ahead of P. R is between P and S.
If S is at the end of the queue, who is at the front of the queue?
Solution
S is at the end
→ order is _ _ _ S
R is between P and S
→ the order of those three from front to back must be P, R, S.
Q is ahead of P, and only four people are there
→ Q must stand before P.
So full order (front → end):
Q, P, R, S,
hence Q is at the front.
