Answer 2

Answer:

A=15 and B = 45.

Step-by-step explanation:

The age of A =1/3 B.

After 15 years the age of A and B would be (A+15) and (B+15).

According the problem ,

(A+15) = (B+15)/2

Further solving the above equation and substituting A =1/3 B.

B/3+15 = (B+15)/2

(B+45)/3 = (B+15)/2

2(B+45) = 3(B+15)

2B+90=3B+45

3B-2B= 90–45

Therefore B=45.

A=1/3 of B i.e 1/3*45=15.

So age of A=15 and B = 45.
