P, Q, R, S and T are five friends. The mean of weights of P, Q, R and S is 50 kg, whereas the mean of weights of Q, R, S and T is also 50 kg. Which of the following statements is/are correct?
1. The weight of T is 50 kg.
2. The weights of P and T are equal..
Select the correct answer using the code given below:
Explanation:
- The total weight for P, Q, R, and S is 4 times 50 = 200 kg.
- The total weight for Q, R, S, and T is also 4 times 50 = 200 kg.
- Since both groups (one including P and the other including T) have identical total weights, it implies that P and T must weigh the same.
