Question

A family has two children along with their
parents. The average of the weights of the
children and their mother is 50 kg. The
average of the weights of the children and
their father is 52 kg. If the weight of the
father is 60 kg, then what is the weight of the
mother?​

Answer 1

Answer:

54kg

Step-by-step explanation:

Children = C

Mother = M

Father = F

(C + M)/3 = 50

C + M = 50 x 3

          = 150

(C + F )/3 = 52

C + F = 52 x 3

         = 156

C = 156 - F

   = 156 - 60

   = 96kg

C + M = 150

M = 150 - 96

   = 54kg
