Answer»

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
