Let x be the age of the person
20 years later his age will be thrice the age before 10 years. So
x+20=3(x-10)
2x=50
x=25

Let the present age of man = x years
20 years later, the man will be three times as old as he was 10 yr ago
x+20 = 3(x-10)
=> x + 20 = 3x - 30
=> x - 3x = -30 - 20
=> -2x = -50
=> 2x = 50
=> x = 50/2 = 25
Thus, the present age of the man is 25 years.

Thus, the present age of the man is 25 years.
