Question
The average weight of a group of five persons, A, B, C,
D, and E is 80 kg. If another person K joins the group then the average weight of the group is decreased by 6.5 kg, then find the weight of K.Solution
Total weight of A, B, C, D, and E together = 80 Γ 5 = 400 kg Weight of K = 73.5 Γ 6 β 400 = 441β 400 = 41 kg
