Question

The age ofRahul and haroonare in the ratio 5:7
Four years later the total age 56. Find the present age

Answer 1

Answer:

present age of rahul = 20 year

present age of haroon = 28 year

Step-by-step explanation:

age of Rahul and haroon are in the ratio 5:7

let present age of rahul = 5x

let present age of haroon = 7x

Rahul age four year later = 5x+4

Haroon age four year later = 7x+4

Four years later the total age 56

$5x + 4 + 7x + 4 = 56$

$x = 4$

present age of rahul = 5x = 5*4 = 20 year

present age of haroon = 7x = 7*4 = 28 year

Answer 2

let Rahul age is =5x. haroon's age = 7x.

ATQ

(5x + 4)+(7x + 4)=56

5x + 7x + 8=56

12x = 48

x =4

now

rahul's present age 5 x 4= 20

haroon's present age 7 x 4= 28
