Ravina age=24years

ravina three times as old as Alisha

Answer 2

Answer:

six years ago

Step-by-step explanation:

let x be the year; then,

12- x = 24

            x

-x *x = 24 - 12

-2x   = 24 - 12

-2x   = 12

 -x    =12/2

  -x   =6

   x   =-6

NOTE:- The answer came in negative sign because in question it is asked about the past. You can replace x with -x according to question; answer will remain same.
