Question
Average weight of a team of 13 persons is 33 kg. When
one more person joins the team, the average weight of the team increases by 4 kg. Find the weight of new personSolution
Sum of weights of 13 persons = 33 × 13 = 429 kg Sum of weights of 14 persons = (33 + 4) × 14 = 518 kg Weight of new person = 518 – 429 = 89 kg
