Answer 1

Answer:

A-35 B-15

Step-by-step explanation:

A=B+20

A-5 = 3(B-5)

B+20-5 = 3B-15

2B=30

B=15

A=15+20=35

Answer 2

Answer:

let present age of B be x years

so present age of A= x+20 years

5 years ago

age of B= x-5 years

age of A = (x+20) -5= x+15 years

however it is given that age of A five years ago= 3(x-5) years= 3x-15 years

B.T.P

x+15= 3x-15

or 2x= 30

or x= 15

therefore present age of B= 15 years and

present age of A= 35 years
