Question

Jamie is 3 times as old as her sister Penny .In 2 years Jamie will be twice as old as Penny .How old are Jamie and Penny now

Answer 1

Well i think this is right;

If jamie is 3 times Pennys age, and in two years he is twice as old as her i would say she is 2 because; 2 * 3 = 6

2 years later Penny would be 4, because she was 2 at the time. And because Jamie was 6 he will become 8. That means he was three times her age. And then in two years twice his age. 

So now Jamie is 8 and Penny is 4.
Hope that helps!
