The mean weight of six boys in a group is 48 kg. The individual weights of five of them are 51 kg, 45 kg, 46kg and 44 kg. The weight of the 6th boy is
Given:
Mean weight of 6 boys = 48 kg
Let the weight of the 6th boy = x kg
Mean weight =
⇒
⇒ 235 + x = 48 × 6 = 288
⇒ x = 288 – 235 = 53 kg
Hence, the weight of the 6th boy = 53 kg.
