Let the present age of Radhika be x and then that of her mother will be 4x
After 5 years,
Radhika's age= x + 5
Her mother's age =4x+5
So,let us put these ages as eqns.(Radhika's age)3 = her mother's age
(x+5)3 =4x+5
3x+15=4x+5
4x-3x =15-5
x = 10
So, we have found the value of x which is radhika's present age .
Then, present age of her mother is
4x= 40.
