Answer 1

Answer:

Their persent ages ( 5 × 4 ) = 20 years and (7 × 4) = 28 years

Step-by-step explanation:

let present ages of Ryan and Karan be 5x and 7x

after 4 years Ryan age = 5x + 4

after 4 years karan age = 7x + 4

A/ Q

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 56 -8

12x = 48

x = 48/12

x = 4
