Given:
The age of the father is 4 times of his son.
5 years ago, the age of the father was 5 times of his son.
Solution:
Let 4x = current age of the father, x = current age of the son
5 years ago, the age of the father was 5 times of his son.
4x – 5 = 5(x – 5)
4x – 5 = 5x – 25
x = 20
The current age of the Father = 4(20) = 80 years.
