There are 20 bagels in a bag. If 15 of the bagels have garlic and 10 of the bagels have onion, what is the minimum number of bagels that have both garlic and onion?

Answer 1

Since there are only 20 bagels in the bag, this means that 5 bagels have both garlic and onion. 10 have only garlic, and 5 have only onion. Therefore, the minimum number of bagels you need to have to have both onion and garlic is 11.
