ANSWER :
_________
Let present age of Aman's son be x years.
Then, the present age of Aman will be 3x.
Ten years ago,
Aman's son age = ( x - 10 ) years.
Aman's age = ( 3x - 10 ) years.
ACCORDING TO THE QUESTION,
5( x - 10 ) = ( 3x - 10 )
5x - 50 = 3x - 10
5x - 3x = 50 - 10
2x = 40
x = 20 years.
=> Age of Aman's son = 20 years.
=> Age of Aman = 20 × 3 = 60 years.
