A Correct answer
Explanation

Sum of weights of P and Q = 38 * 2 = 76 kg. Sum of weights of P, Q, and T = 49 * 3 = 147 kg. Weight of T = 147 - 76 = 71 kg.

AI explanation

The total weight of players P and Q is 38 * 2 = 76 kg. When coach T is included, the total weight becomes 49 * 3 = 147 kg. The coach's weight is the difference between these totals, which is 147 - 76 = 71 kg.
