Question

Ages of rahul and haroon are in the ages of 5:7 after 4 years sum of their ages will be 56 find their present ages

Answer 1

Answer:

20 and 28

Step-by-step explanation:

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

12x + 8 = 56

12x = 48

x = 4

5*4 = 20

7*4 = 28

Answer 2

rahul is 20 years and Haroon in 28 year old

as

let the age of rahul be 5x and age of Haroon be 7x

after 4 years there age will be 5x +4 and 7x +4

so, the sum of there ages are 56

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

12x + 8 = 56

12x = 56 - 8

12x = 48

x = 48/12

x = 4

rahul is 5x so 5 *4 = 20

Haroon is 7x so 7*4 = 28
