Question

john is now four time as old as annie was six years ago how old is annie today if john is 20years old?​

Answer 1

Answer:

present age of Annie=x years

six years ago Annie age=x-6

present age of john=four times as old as Annie was six years ago

present age of john=4*(x-6)

according to the problem present age of john is 20 years

4*(x-6)=20

dividing by 4 on both sides

4*(x-6)/4=20/4

x-6=5

adding 6 on both sides

x-6+6=5+6

x=11

the present age of Annie=11 years
