let son's present age is x years. 
hence, father's present age is (3x + 3) years. 
after 3 years, son's age will be (x + 3) years. 
and father's age will be (3x + 6) years. 
but given that after 3 years father's age will be ten years
more than twice the son's age. 

(3x + 6) = 2 * (x + 3) + 10 

3x + 6 = 2x  + 16 

x = 10 

Therefore, father's present age is 33 years.
