Directions: Read the following statements and answer the question:
Five cities P, Q, R, S and T are connected by different modes of transport as follows:
P and Q are connected by boat as well as rail.
S and R are connected by bus and boat.
Q and T are connected by air only.
P and R are connected by boat only.

If a person visits each of the places starting from P and gets back to P, which of the following places must he visit twice?
  1. Q
  2. R
  3. S
  4. T

Answer and explanation

Correct answer: B - R
Links: P-Q, P-R, Q-T, T-R, R-S. S connects only to R, so a round trip from P through all cities, e.g. P-Q-T-R-S-R-P, must pass R twice.
