Let Aman's present age be x and his son's present age be y
Aman's age is three times his son's age
Therefore x = 3y
Ten years ago Aman was five times his son's age
10 years back Aman's age was x-10
10 years back Aman's son's age was y-10
Therefore x-10 = 5(y-10)
x - 10 = 5y - 50
replace x = 3y
Therefore 3y - 10 = 5y - 50
Therefore 2y = 40
Therefore y = 20
Replacing y = 20 in x = 3y
x = 3 × 20
x = 60
Hence Aman's age is 60 and Aman's son's age is 20.
Hope this is helpful
