To Find : a) What is the age of Ridhima’s father?.

b) what is her grandmother's age?

Solution:

Ridhima Grandmother  age = Twice Ridhima Father Age

Ridhima Age + Ridhima Father Age + Ridhima Grandmother  age =  120

Ridhima Age =  15 Years

Ridhima Grandmother  age = Twice Ridhima Father Age

=> 15 + Ridhima Father Age + 2 x Ridhima Father Age = 120

=> 3  x Ridhima Father Age   = 105

=> Ridhima Father Age   =  35

Ridhima Father Age   =  35

Ridhima Grandmother  age  = 2 x 35 = 70 Years

Ridhima Father Age   =  35  YEARS

Ridhima Grandmother  age  = 70 YEARS
