The average weight of 5 men decreases by 3 kg when one of them weighing 150 kg is replaced by another person.
Concept used:
Total = Average × Number of entities
Calculation:
Let the initial average of 5 men and the weight of the new person be N and P respectively.
According to the question,
5N - 150 + P = 5(N - 3)
⇒ P = 150 - 15
⇒ P = 135
∴ The weight of the new person is 135 kg.
