Chapter 48 The Smart Deal

In the desert, water is very precious; even a liter of water, which is not too much, sometimes causes mutual killings.There was a water merchant who filled a large skin bag with 25 liters of water. When he was traveling through the desert, he met a customer who wanted to buy 19 liters of water and another customer who wanted to buy 12 liters of water.The amount of water is not enough to sell to two people, so it can only be sold to one party; and he hopes to end this transaction as soon as possible in this scorching desert.Assuming that it takes 10 seconds for the water merchant to pour out a liter of water from the leather bag; then which customer will he sell it to?

[Answer: The guest who wants to buy 12 liters of water.At first glance, it may make people think that only 25 liters are poured out of the 6-liter skin bag, and the rest is sold to the first customer; but because the skin bag contains 25 liters of water, only the water merchant knows, The guest does not know.

Anything can be considered a major premise.In terms of transactions, letting customers understand is the major premise.There may be many ways to present this question, but the correct answer is the one that first satisfies the major premise. ]
