Question

adil tells his dad that the ratio of present ages 8:3 after 10 years their ages will be in the ratio of 2:1

Answer 1

Step-by-step explanation:

present age

let adil's age be x

and his father be y

x/y = 3/8

x = 3y/8 _____ equation (1)

after ten years

x+10/(y+10) = 1/2

2x +20 = y +10

substitute the equation (1)

2(3y/8) = y -10

3y = 4y-40

y = 40

x = 15

hence

present age is 15:40

so 3:8

after ten years

15+10:40+10

25:50

1:2
