. The present age of a father is three years more
than three times the age of the son. Three years hence, father's age will be 10 years more than twice the age of the son. Determine their present ages.
Let, present age of son =x
And, present age of father = 3x+3
3 years later, age of son = x+3
Age of father = 3x+3+3=3x+6...(i)
According to the given condition, age of father =10+2(x+3)......(ii)
From (i) , (ii) we get,
Present age of son =10
Present age of father =3(x+3)
The present age of son is 10 years and that of father is 33 years.
