Question

the present age of mother is 3 times the present age of her son.after 15 years the age of mother will be twice to the age of her son .find their present ages​

Answer 1

Step-by-step explanation:

let the age of son be x

Age of mother =3x

After 15 years,

Age of son =x+15

Mother's age =3x+15

According to the question

2(x+15)=3x+15

2x+30=3x+15

2x-3x=15-30

-x=-15

x=15

Age of son =15 years

Age of mother =3*15=45 years
