Question
A boy’s age is 130% of what it was 10 years ago, but
65% of what it will be after 10 years. What is his present age?Solution
Let the present age of boy be ‘x’ years. 130% of age of boy 10 years before = 65% of age of boy after 10 years => (130/100) × (x - 10) = (65/100) × (x + 10) => 130(x - 10) = 65(x + 10) => 130x - 1300 = 65x + 650 => 65x = 1950 => x = 30 yrs
