Let Banu's age=a; Binu's age =i

As per conditions,

a=i+20;

a+5=2(i+5)

or,i+20+5=2i+10

or,i+25=2i+10

or,2i-i=25-10

or,i=15

Therefore a=20+15

or, a=35

Banu's age=35 years

Binu's age =15 years

As per conditions,

a=i+20;

a+5=2(i+5)

or,i+20+5=2i+10

or,i+25=2i+10

or,2i-i=25-10

or,i=15

Therefore a=20+15

or, a=35

Banu's age=35 years

Binu's age =15 years

Let banu age be x there4

binu age =y

there4 x=y+20

in 5 yrs.

ba age =x+5

bi age =y+5

x+5=2(y+5)

solving

y=15 and x=35

binu age =y

there4 x=y+20

in 5 yrs.

ba age =x+5

bi age =y+5

according to ques,

x+5=2(y+5)

solving

y=15 and x=35
