Question
A boy’s age is 125% of what it was 8 years ago,
but 75% of what it will be after 8 years. What is his present age?Solution
Let the present age of boy be ‘x’ years. 125% of age of boy 8 years before = 75% of age of boy after 8 years => (125/100) × (x - 8) = (75/100) × (x + 8) => 125(x - 8) = 75(x + 8) => 125x - 1000 = 75x + 600 => 50x = 1600 => x = 32 yrs.
