Question
Two numbers are, respectively, 10% and 25% more than the
third number. The ratio of the two numbers is:Solution
let the third number be p A = p + 10% of p ⇒ A = 110p/100 = 11p/10 B = p + 25% of p ⇒ B = 125p/100 = 5p/4 ⇒ A : B = 11p/10 × 4/5p ⇒ A : B = 22 : 25 ∴ The ratio of A and B is 22 : 25
