Question

The present age of rajeev and monica are in ratio 5:12. 17 years ago, the ratio of their ages was 4:1. Find their present ages​

Answer 1

Step-by-step explanation:

let x be the common multiple in the ratio 5:12.

therefore age of rajeev = 5x and age of monica be 12x.

age of rajeev 17 years ago = 5x - 17 and age of monica 17 years ago = 12x - 17.

thus,

age of rajeev÷ age of monica (17 years ago) = 4÷1

5x - 17 ÷ 12x - 17= 4÷1

(5x - 17) x (1)= (12x - 17) x (4)

5x - 17= 48x - 68

68 - 17 = 48x - 5x

51÷ 43 = x
