Question

13) The ratio of ages of 2 people Amit and Brijesh is 4:5. After 6 years from now, the ratio will be 6:7. Find out their Present ages​

Answer 1

Answer:

x=12,y=15

Step-by-step explanation:

Let amit age is x

let Brijesh age is y

x/y=4/5

5x=4y

5x-4y=0———1

x+6/y+6=6/7

7(x+6)=6(y+6)

7x+42=6y+36

7x-6y=36-42

7x-6y=-6———2

from 1 & 2,we get

1×3=15x-4y=0

2×2=14x-12y=-12

x=12

sub x=12 in 1

5(12)-4y=0

60-4y=0

-4y=-60

y=-60/-4

y=15
