Question

Five friends P, Q, R, S and T went camping. At night, they had to sleep in a row inside the tent. P, Q and T refused to sleep next to R since he snored loudly. P and S wanted to avoid Q as he usually hugged people in sleep. Assuming everyone was satisfied with the sleeping arrangements, what is the order in which they slept?

Correct answer (A) RSPTQ Solution The conditions are: 1. R cannot be next to P, Q, or T. This means R must be next to S. 2. Q cannot be next to P or S. Let's evaluate the options: (A) RSPTQ: R is next to S (OK). Q is next to T (OK). P is next to S and T (OK). R is not next to P, Q, or T (OK). Q is not next to P or S (OK). This arrangement satisfies all conditions. (B) SPRTQ: R is next to P and T. This violates condition 1. (C) QRSPT: R is next to S and P. This violates condition 1. (D) QTSPR: R is next to P. This violates condition 1. Thus, the correct order is RSPTQ. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
