Question

is the age of Rahul and Haroon are in the ratio of 5:7 . after 4 years the sum of there age is 56 years then when is there present age?​

Answer 1

Answer:

Let Rahul's age = 5x

Let Haroon's age = 7x

A/Q (5x+4)+(7x+4) = 56

5x+7x+8 = 56

12x = 48

x = 4

Rahul's age = 5x = 5x4 = 20 years

Haroon's age = 7x = 7x4 = 28 years

Answer 2

Answer:

rahul age 20 year

and haroon age 28 year

Step-by-step explanation:

let rahul present age=5x

and haroon present age =7x

four years after

rahul age 5x+4

haroon age 7x+4

5x+7x+4=56

12x+56-8=48

12x=48

x=4

so,rahul age=5x×4=20year

and haroon age =7x×4=28year
