Question

A grandmother is six times older than her granddaughter. If she is 75 years older than her grandson. Find their present ages.​

Answer 1

Answer:

6x-x= 75

5x = 75

x = 15

Hence granddaughter is 15 years and grandmother is 90 years

Answer 2

Answer:

Let age of granddaughter be x. then,

grandmother's age = x+75

6x = (x+75)

x= 15

Granddaughter's age = 15 yrs

Grandmother's age = 90 yrs
