Detailed Solution
Download Solution PDFLet the present age of son be x years
∴The present age of father = 4x years
After 10 years
Age of son = (x + 10) years
Age of father = (4x + 10) years
According to the given condition
4x + 10 = 3(x + 10)
4x + 10 = 3x + 30
4x – 3x = 30 –10
x = 20
∴Present age of son = 20 years.
and present age of father = 4x = 4 × 20 = 80 years.
