Three people spent 30 yuan in a hotel for one night. Each of them paid 10 yuan enough. 30 yuan gave it to the boss. Later, the boss said that today's discount is only 25 yuan.

1. They each spent nine yuan, so a * * * spent twenty-seven yuan, right ~ ~ Remember ~ ~ Remember ~ ~

2. But in fact, it only needs 25 yuan ~ ~ ~ wood and wood ~ ~

3. So 27-25=2 was stolen by the waiter ~ ~ ~ Done.

The key to solving the problem is that tonight is not a night in 30 yuan. They spent 27 yuan as soon as they got married, so it's wrong to care about 30 yuan ~ a dead end ~

In fact, if you reach the age of 30, there is another solution:

They paid 30 as soon as possible, but in fact they only needed 25. They found 3 pieces, stole 2 pieces, 25+3+2=30 ~ Did you find the 30 pieces you wanted ~

In fact, it's also a question of learning ~ isn't it ~ ~
