Therefore, Present age of Banu = x+20

After 5 years,

Age of Binu = x+5

Age of Banu = (x+20)+5

= x+25According to question ,

x+25 = 2 (x+5)

x+25 = 2x + 10

25 = 2x+10 - x

25 = x+10

25 - 10 =x

15 = x

or x= 15

Hence Present age of Binu = 15 years

and Present age of BAnu = x+20

= 15 + 20

=35 Years !!

Then the present age of Banu is 20 + x.

Age of Banu after five years = 25 + x

Age of Binu after five years = 5 + x

After five years, 25 + x = 2 (5 + x)

= 25 + x = 10 + 2x

25 - 10 = 2x - x

15 = x
