answer this question plz fast it is very important​

Answer 1

Step-by-step explanation:

let the common multiple of the radio be x

Harry's age= 7x

Hari´s age = 5x

acc. to sum

$\frac{5x + 4}{7x + 4} = \frac{3}{4}$

$20x + 16 = 21x + 12$

$x = 4$

therefore their present ages are 28years and 20 years respectively

Answer 2

Hari: 5x

Harry: 7x

$\frac{5x + 4}{7x + 4} = \frac{3}{4}$

4(5x+4)=3(7x+4)

20x+16=21x+12

20x - 21x= 12-16

-x=-4

x=4

Hari=5x=5×4= 20

Harry=7x=7×4=28
