• Average of weight of two children and their mother (i.e. total 3 members) = 50.

• So, the sum of the weight of two children and mother = C1 + C2 + M = 50 × 3 = 150 ... (1) (where C1 and C2 are the weights of two children and M is the weight of the Mother)

• Again if the weight of the Father is F, we have C1 + C2 + F = 52 × 3 = 156 ... (2)

• Now it is given that the weight of the father = F = 60.

• By putting this value in equation (2), we have C1 + C2 = 156 - 60 = 96.

• Again by using equation (1) we have M = 150 - 96 = 54 kg.
