“Finding Piso” Three friends decided to eat in a restaurant. Each has P10. They agreed to cheap in their money (amounting to P30) and chose a menu which they could eat together. After finishing their meal, they’ve learned that their bill amounted to P25. This is what they did with the remaining P5. Each one got P1 back and they gave the waiter P2 as tip. Here’s the puzzle. If each of them contributed P10 and got back P1 later, it means that each one spent P9. If we multiply P9 by 3 (friends), it means that they spent P27. Adding the P2 they gave to the waiter to P27 they spent, makes it P29. If their money from the start is P30, where is the P1? Can we really find the missing P1 in the puzzle? Why or why not? “Finding Piso” Three friends decided to eat in a restaurant. Each has P10. They agreed to cheap in their money (amounting to P30) and chose a menu which they could eat together.
