Anyone knows how to solve this?
You go to two friends and borrow 25$ from each. With 50$, you go and spend 47$. You decide to start paying your debts to your friends so you give each one a dollar and keep one for yourself. Now you owe 24$ to each of them. 24+24=48, plus the dollar you kept, 49$. How do you start with 50$ and end up with 49$?
