Answer 1

Answer:

Sita's present age is 9

Geeta's present age is 3

Step-by-step explanation:

Let Sita's age be x.

Let Geeta's age be y.

According to the given condition,

    $x=3y$ → 1

After 9 years,

Sita's age = 9+x

Geeta's age=9+y

According to the given condition,

   $x+6+9=2(y+9)\\x+15= 2y+18\\x-2y=18-15\\x-2y=3$→ 2

On substituting 1 in 2,

 $3y-2y=3\\y=3$→ 3

On substituting 3 in 1,

$x=3*3\\x=9$
