Answer 1

Answer:

20 years I did it on my own

Step-by-step explanation:

the question is wrong it should be like ten years from now,sheila will be twice as old as sanjay

Let the Present age of Sanjay (in Years ) = x

Therefore , Present age of Sheila = x+15

After 10 years ,

Shielas age = x+15+10

= x+25

sanjay's age = x+10

According to question ,

x+25 = 2(x+10)

x+25 = 2x + 20

25 = 2x + 20 - x

25 = x+20

25 - 20 =x

5 =x

or x=5

Hence Present age of Sanjay = 5 years

and Present age of Shiela = x+15

= 5+15

= 20 years
