Amy lives on a street with 12 houses. Every day she gets more letters than are delivered to any other house. If 57 letters are delivered to her street today, what is the smallest number of letters Amy could receive?
Answer:
6 ............. The nearest multiple of 12 below 57 is 48. This means 48/12 = 4 letters per house (including Amy's). This leaves 9 letters. Seven people get one more letter, and Amy gets two more.
