Answer 2

Answer :

•  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
