Question

A is 15 years older than B.ten years ago,A was four times B's age.What are their ages now?

Answer 1

Answer:

B is 15 years old and A is 30

Step-by-step explanation: let b= age of B. Then b+15=age of A

10 years ago, B was b-10 and A was (b+15)-10

so therefore

(b+15)-10=4(b-10)

b+5=4b-40

3b+45

b=15
