Answer:
36 & 9 year
Step-by-step explanation:
Let the present age of his son be 'a'. So his age should be 4 times of a i.e. 4a.
After 18 year ago:
Age of Mohan = 4a + 18
Age of his son = a + 18
That time, he will be two times of his son's age:
= > 4a + 18 = 2(a + 18)
= > 4a + 18 = 2a + 36
= > 4a - 2a = 36 - 18
= > 2a = 18
= > a = 9
So, present age of :
Mohan = 4a = 4(9) = 36 year
His son = a = 9 year
