Hello people! Hahaha.. The blog no post ah, so I decided to post some kind of question, and you all can try to solve it. Answer of previous question will be posted at the next post. Haha.. Better than the blog kong kong de ma? LOL! And I also feel very sian le.. Hahaha..
Q) There were 3 customers, a group of friend, eating at a restaurant. Each of them bought $10 food. So after eating, they paid $10 each. They passed $30 to the waiter, the waiter passed the $30 to the manager. Then the manager decided to give discount to the customers. He gave back $5 to the waiter. However, the waiter decided to keep $2 for himself. So he kept $2 out of $5 that the manager gave back into his pocket, and gave back $3 to the customers. The customers shared $3 among themselves, so each of them took $1 each.
Each of the customers paid $10, and received $1 back, so they paid $9 in the end. There were 3 customers, so they paid $27. And the waiter decided to give back the $2 to the manager, (he cheng ren cuo wu ma?) Summing up them, it's $29. Then where is the $1 gone?
Hint: Try using some visual objects to represent the money, and move them around.
