Three farmers went to town for a meal. They all chose the menu of the day, which cost ten pounds. After the meal they each paid the waitress 10 pounds. Back in the kitchen, the owner told her that the total price was only 25 pounds. Before the waitress went back to the farmers, she put 2 pounds in her own pocket. She explained that they had paid too much and refunded each farmer 1 pound. Happily, everything turned out fine, because each farmer had paid 10 minus 1, i.e. nine pounds. Three times nine plus the two pounds in the waitress's pocket makes exactly 29 pounds. Where did the last pound go?
... and the answer...
This is the wrong calculation. The 2 pounds should be subtracted, not added tp the 27, to get 25 pounds.
Put another way, the men paid 27 pounds (3 times 9), of which 25 has gone to the owner and 2 to the waitress.
