Question

please solve this . this chapter name is linear equation in one variable . que is. banu is 20 years older than binu. in 5 years,banu will be twice as old as binu .find their present age

Answer 1

Binu is 25 and band is 45

Answer 2

Binu age=x
Banu age = x+20
after 5 year
x+5=2x+20
-2x+x=-5+20
x=15
therefore banu's present age
=15+20
=35
and banu's age
=15
