Queue Arrangement Problem
Given Information:
Four people: P, Q, R, S.
Q is ahead of P.
R is between P and S.
S is at the end of the queue.
Reasoning:
S is at the end of the queue: This means S is the last person.
R is between P and S: Since S is last, and R is between P and S, the order must be P, R, S.
Q is ahead of P: This means Q comes before P. Combining this with the previous deduction, the order becomes Q, P, R, S.
