Question
Average weight of a team of 16 persons is 37 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 16 persons = 37 × 16 = 592 kg Sum of weights of 17 persons = (37 + 4) × 17 = 697 kg Weight of new person = 697 – 592 = 105 kg
