Question

Kevan is 6 years younger than Katie. Melanie is twice as old as Kevan. How old are all three siblings?

Answer 1

Kevan is 8
katie is 14
Melanie is 16

I think this is the answer.

Answer 2

Let's start by narrowing it down to make it simpler:

Kevin is 6 years younger than Katie

Melanie is twice as old as Kevin.

So, to start off with, Melanie is twice as old as Kevin. That would make Melanie 12 years old, and Kevin 6 years old. I'm not too sure about Katie, however. But this is what I got:

Kevin: 6 years old
Melanie: 12 years old
Katie: ?

Hopefully that helped a little! :)
