Answer:
(c) 10 years
Step-by-step explanation:
Let the present age of the son be x.
So, the present age of the father = 3x
After three years,
Age of the son = x+3
Age of the father = 3x+3
Now, according to the question,
3x+3 = 2(x+3)+7
=> 3x+3 = 2x + 6 +7
=> 3x+3 = 2x+ 13
=> 3x- 2x = 13-3
=> x = 10
So, the present age of the son = x = 10 years.
