Answer 2

let the age of ani be x and biju's age be y

A/q

x-y =3 (equation 1st)

now,

we have been given that

dharam 's age =2x

Cathy's age =y/2

so that

2x-y/2 =30(equation 2nd)

now by solving these two equation, we get

X=19

and by putting this value of x=19 in eqation 1st or 2nd we get

y=16
