Question
The average weight of a team of 5 players is 75 kg. If
the heaviest player leaves the team, the average weight becomes 70 kg. Find the weight of the player who left.Solution
Let the weight of the person who left be βxβ kg. So, x + (75 β 5) Γ 4 = 5 Γ 75 x + 70 Γ 4 = 375 x + 280 = 375 x = 375 β 280 x = 95 kg So, weight of the person who left was 95 kg.
