Question

, the daughter is half the age of the mother and the grandmother is twice the age of the mother. The sum of their ages is 140. Write an equation to represent this situation and solve the equation to find the ages of each member of the family.

Answer 1

Answer:

let the age of the mother be x years then age of daughter is x/2 years and age of grandmother will be 2x

x + 2x + 4x =140

7x =140

x = 20

age of daughter = 20 years

age of mother = 40 years

age of grandmother = 80 years
