Answer:
45 years
Step-by-step explanation:
let present age of mohan's son be x.
then mohan's present age = 3x
Age of mohan's son after 5 yrs = (x+5)
Age of mohan after 5 yrs= 5/2(x+5)
Also age of mohan after 5 yrs = (3x+5)
5/2(x+5) = (3x+5)
5(x+5) = 2(3x+5)
5x+25 = 6x+10
25-10 = 6x-5x
15=x
we have, x=15
therefore, the present age of mohan's son = x = 15 yrs
present age of mohan = 3x = 3×15
= 45 years
