Answer provided by our tutors
George's father is cube root 5 times younger than his grandfather.
father's age = cube root 5 x grandfather's age.
We know that his grandfather is 84 years old.
So father's age = cube root 5 x 84.
Now George is 3 times younger than his father:
George's age = father's age / 3
= cube root 5 x 84 /3
= 47.88
= 48
