Answer:Ambuj=48yrs, Avinash=18yrs

Step-by-step explanation:

Let Ambuj present age be x

Let Avinash present age be y

>3yrs ago,

>Ambuj was x-3, Avinash was y-3

>x-3=3(y-3)

>x-3=3y-9

>x-3y=-6.......(1)

>x:y=8:3

>x=(8y)/3.......(2)

>Substitute (2) for x in (1)

>(8y/3)-3y=-6

>Multiply through by 3

>8y-9y=-18

>-y=-18,y=18

>Then x=(8*18)/3=48

Ambuj=48yrs, Avinash=18yrs
