Description for Correct answer:
Let x be the present age of the son.
So father's age will be 56-x
After 4 years the age of the father will be 3 times that of his son
(56−x+4)=3(x+4)(56−x+4)=3(x+4)
56−x−3x−12+4=056−x−3x−12+4=0
4x = 56 -8 = 48
x = 12
The age of the son is 12 years.
The age of his father is 44 years.
