Answer 1

Step-by-step explanation:

HERE IS YOUR ANSWER.

LET THE AGE OF VANI BE , x Years old.

Rishi age will be ,2x.

Now case 1.

10 years ago means

2x-10 = x-10..

age was thrice of vani then,

3(2x-10)=x-10.

6x-30 =x-10.

6x-x= -10+30

5x=20

x=20/5

x=4

vani age =4 years

Rishi age = 4×2=8 years
