The ratio of John's savings to Alice's saving is 1:2. If their mum gave $1000 to each of them, John had 2/5 as much money as Alice. What is John's saving?
Your ratio of 2/5 may not be correct! It could be either 2/3 or 3/5 or something else! Check it carefully.
Write as an equation:
\({2 \over 5} ={ x + 1000 \over 2x+ 1000}\)
Solving for x, we find John originally had \(\color{brown}\boxed{-3,000}\) dollars.
