Answer 2

Answer:

Step-by-step explanation:

The difference between them in present is 5 years

Let first sister be x year old

And another will be x-5 year old

10 years ago

Age of first sister was x-10 years

Age of another sister will be x-15 years old

As given relation in question ,

      The elder sister is twice of another sister so

       x-10=2(x-15)

       x-10=2x - 30

       x-2x= -30 + 10

       -x = - 20

       x = 20

So x=20

The age of elder sister is 20 years

And age of another sister is 15 years
