Question

The ratio of present ages of Gopal and Hari is 4:5 after 6 year there ratio of there ages will 6:7 . What is the present age of hari?​

Answer 1

Step-by-step explanation:

Given ratio of ages = 4:5 So let their ages be 4x , 5x

After 6 years...

4x + 6 : 5x + 6 = 6:7

7(4x + 6) = 6(5x + 6)

= 28x + 42 = 30x + 36

= 2x = 6

x = 3

So 4(3) = 12 and 5(3) = 15

Present age of Gopal is 12 and that of Hari is 15

gopal`s age = 4x +6

hari`s age= 5x+6

by cross multiplication,

(4x+6)7=(5x+6)6

x=3
