Question

Ten years ago, P was half of Q's age. If

the ratio of their present ages is 3:4, what will
be the total of their present ages?​

Answer 1

Answer:

Let their ages before 10 years be x and y

Now x =y/2

And after 10 years x+10/y+10 =3/4

3y-4x=10

Put x=y/2

We get y=10

And x=5

No their present ages are 15 and 20 and their sum of ages is 35
