Chapter 577

"You ask!" Panda ball looks at Laifu nervously with black eyes and listens attentively to Laifu's questions.

"Lao Tuo bought a chicken for eight gold coins, sold nine gold coins to me, and then he thought it was not worthwhile. He bought it back for ten gold coins, and then sold eleven gold coins to Nicole. What I want to ask is, how much money did old Tuo make?" Asked Lai Fu.

You have to let this boy know a little bit strong, so Laifu chose a slightly difficult topic.

The ball broke his fingers and calculated again and again. Finally, he even used his toes. Then he replied with uncertainty: "two gold coins?"

"Are you sure?" Lai Fu sneered.

"If two are wrong, they are three. They are three gold coins. At first, there are eight gold coins, and then eleven gold coins. I am sure they are two." Ball ball loud answer, at the beginning, there are some guilty, more and more confidence behind.

"Wrong, two."

Black crow Brad Pigan calculated and determined that the answer of Laifu was correct. It was really two gold coins.

Then Mr. Lai Fu tells you the algorithm of this problem.

This topic is more popular. You have eight gold coins in your backpack. You buy a chicken, and then you have nine gold coins to sell.

At this time, you have 9 gold coins in your backpack, and then you ask someone else to borrow a gold coin to buy back the chicken. After you sell it, there are 11 gold coins in your backpack, and you pay off the debt of one gold coin. There are ten gold coins in your backpack. Compared with your original eight gold coins, you really earned two.

Or you simply don't have to be so troublesome. You bought two chickens with eight gold coins and ten gold coins twice, which cost a total of 18 gold coins.

You sold the two chickens for nine gold coins and eleven gold coins for twenty gold coins.

This will also work out the correct answer.

The ball was originally the right answer, but it was not very confident, was sneered at by Lai Fu and changed a more intuitive answer.

The apostles didn't understand it, but at least by comparing the two methods, we finally got something.

If you have data to show, you may be able to see intelligence quotient + 1 + 1 and other things on each other's heads. Teacher Laifu is indeed teacher Laifu, and the questions put forward by him test IQ very much.

Unlike the ball, the ball's title is purely a trap.

"It's your turn." Lai Fu lifted his chin, little boy, and I dare to compare IQ.

"Why does one cow need a hundred gold coins and two oxen need 500 gold coins?" Another question comes to Panda ball. It has answered correctly just now, so there is no big gap between panda ball and Laifu.

"Good quality of cattle?" Asked Lai Fu.

"Are you sure that's the answer, like Eric in the back two cows?" Here, Fu is trying to guide the ball.

"Yes, that's the answer." Laifu nodded.

"Ha ha, wrong. One head of cattle is common, and two headed cattle are more precious, boss. You are so stupid." The ball used a small trap to cheat to win Laifu. Don't be too happy in my heart.

Although its score is still one point behind, but at least it saw the hope of winning.

"Oh, that's what it looks like." Laifu was suddenly enlightened and then regretted. Only it knew what was true and what was false.

"It's your turn to ask questions. Ask them quickly." The ball urged.

"One rope has two heads, three and a half ropes, how many heads does it have?" Lai Fu thought about it for a while and put forward a relatively simple topic in his mind.

"Eight, ha ha, I've heard about this topic. Half a rope has two heads. Boss, you are so good. I thought you were so good." Obviously, the panda ball can't float any more.

In this way, it's a draw with Rafael's score.

"Then you can work out the problem." Laifu sneers at me. If I beat you to death with a stick, you may not have suffered much. I just want to let you see the hope first, and then lose the gold medal in despair.

"There is a new thing in the monster store. Black bears want to buy it. Black bears are short of five gold coins and white bears are short of one silver coin. However, if two bears buy one, the money is still not enough. Do you know the price of this? How much money do they each have? "The ball knows the critical moment is coming and it has to come up with a killer.

Laifu looked at the black-and-white bear. The two bears were stupefied. Obviously, there was no such thing.

This topic actually is the ball ball this two goods own present compilation?

Although the title is not much high, but if it is really made up of the ball, then the IQ of this product is a little high and frightening.

I don't know if it's a good thing or a bad thing to have such a pet.

"Say it quickly, pidan, and count down quickly." Seeing that Laifu didn't speak, the ball thought that he was finally baffled. That was an excitement.

At first, it falls into the downwind, and then overtakes. This is the proper template of the protagonist in the story."The black bear has no money. The white bear has 4.9 gold coins. There are five gold coins in all, right?" Raffle gave the answer as the black crow Brad's egg began to count down.

Baby, let you know what despair is.

Although the ball is disappointed, it is not desperate. It only needs to answer the following questions from raffle to play overtime.

"Caesar can break a corn every minute. In the orchard, how many corn can Caesar break in five minutes?" asked Lai Fu.

In fact, it has many very difficult problems to solve. It is no problem to make the panda die. Only in order to convince the other party that it has lowered the IQ to the same level for a duel.

"Five, no, wait a minute." The ball is confused. Isn't that easy.

"It's OK. Think about it." Raffle doesn't mind at all.

"A total of five, but it has only one in his hand. The monkey likes to break and throw." Panda ball heard the story of little monkey breaking corn in the bar, and knew the monkey's habits.

Don't ask why people in bars tell such childish stories. I don't know.

"Wrong, where is the corn in the orchard? Are you stupid? You lose." Laifu looks at the proud rebellious panda and gives it a final blow.

"Ah The ball was dumbfounded, but it soon argued, "why can't you plant corn in the orchard? What kind of corn do you like?"

"There are 10 apostles playing hide and seek, four have been found, and how many others are hiding and not found?" Asked Lai Fu.

"Six." The ball's straight answer.

"Five ah, idiot, hide and seek is a person to find, other people hide, you did not play with others yesterday?" To make complaints about the road.

"I I forgot. " Good hit how to do, the ball with two claws to cover his face, was bullied to cry.
