Question
The average weight of a group of five persons, A, B, C,
D, and E is 66 kg. If another person K joins the group then the average weight of the group is decreased by 4 kg, then find the weight of K.Solution
Total weight of A, B, C, D, and E together = 66 × 5 = 330 kg Weight of K = 62 × 6 – 330 = 372 – 330 = 42 kg
