A man’s present age is 125% of what it was 10 years ago, but 83.33% of what it will be after 10 years. Find his present age.

Explanation

• Let present age = x
• x = 1.25(x - 10) => x = 50
• Check: 83.33% = 5/6 of (x+10) => x = (5/6)(x+10) => 6x = 5x + 50 => x = 50
• Both conditions confirm present age = 50 years
