1=5, 2=15, 3=215, 4=2145, then 5=?

Suya chose 1

Requesting more updates: [Why is this happening?]

Here comes the genius! This is a trick question because we've already told him that 1 = 5, so everything else is redundant.

The doorway to the seventh room.

There are 2 horses, 3 cows, and 4 sheep. The total price of any one of them is less than one wen (an ancient unit of currency). If 2 horses are added to 1 cow, or 3 cows are added to 1 sheep, or 4 sheep are added to 1 horse, then the total price of each of them is exactly one wen. What is the price of each horse, cow, and sheep in wen?

There are three spaces below.

Suya filled in 3600, 2800, and 1600.

One day, a pirate ship was hit by a bull falling from the sky. Five unlucky guys were forced to flee to a deserted island, where they found themselves all alone. Luckily, there was a coconut tree and a monkey! They picked all the coconuts and put them together, but it was already late, so they went to sleep. That night, one of the guys quietly got up and secretly divided the coconuts into five portions. He found one extra coconut, so he gave it to the lucky monkey, then secretly hid one portion, mixed the remaining coconuts together, and put them back in their original place. Finally, he quietly went back to sleep. A while later, another guy also quietly got up and secretly divided the remaining coconuts into five portions. He found one extra coconut, so he gave it to the lucky monkey, then secretly hid one portion, mixed the remaining coconuts together, and put them back in their original place. Finally, he quietly went back to sleep. And so on... In short, all five guys got up and did the same thing. Everyone got up in the morning and, each with their own ulterior motives, began dividing the coconuts. This monkey was incredibly lucky; after dividing the coconuts into 5 parts, there was still one coconut left over, so they had to give it to the monkey. The question is, what is the minimum number of coconuts in the pile?

Suya glanced at what was written

The other four boys had some clue, but they had absolutely no idea what this last question meant. They were completely baffled.

Next is the eighth room.

Two blind men each bought two pairs of black socks and two pairs of white socks. All eight pairs of socks are identical in material and size, and each pair has a label attached. The two blind men accidentally mixed up the eight pairs of socks. How can each of them retrieve two pairs of black socks and two pairs of white socks?

Suya wrote that she took apart all the socks and wore one each day.

They soon arrived at the ninth room.

Given: Each airplane has only one fuel tank, and airplanes can refuel each other (note that it's mutual, there are no refueling aircraft). One tank of fuel is enough for one airplane to fly halfway around the Earth. Question: To ensure that at least one airplane can fly around the Earth and return to its starting airport, what is the minimum number of airplanes required? (All airplanes take off from the same airport and must return safely; no intermediate landings are allowed, and there are no airports in between.)

Suya filled 3 boxes.

Doorway to the tenth room

1, 11, 21, 1211, what is the next number?

Suya filled in

Urging for more updates: [Where are the top students?]

Top student: [Still analyzing, she's just too fast.]

The ten questions upstairs have all been answered. Only a little over 10 minutes have passed. Downstairs, there are still 20 minutes until the next round of questions.

"Sister, why don't we go down and see if they need our help?"

The second brother, Su Linxi, suggested it.

"good."

So all five of them went down.

Then they saw five girls, including Kinako, standing at the door of the first room, with a countdown timer on the door showing 18 minutes left.

While waiting, Su Ya walked around and looked at all the other doors. The answer was already in her mind.

Time ticked by.

Eighteen minutes seemed like a long time.

We've finally arrived.

Kinako is about to enter her answer on it again.

William Su winked at a few boys, and they all stopped him.

Kinako was a little angry.

Why are you stopping me?

"If you answer incorrectly this time, the time before the next round will be extended by an hour. Can you bear the consequences? Do you want all of us to accompany you?"

William Su has always been blunt and outspoken; people in the industry call him a "sharp-tongued man."

Kinako: "You."

"That's right. If you can't do it, then let someone else have it. I don't want to get arrested."

While the others remained silent, Chu Kening spoke up.

She didn't want to be arrested. If they were wrong this time, she would definitely be the one arrested. Mumu and Munai were on the same team, and Chu Kexin was too young. Ziling had already been arrested.

"It's you. Get out of the way. We still want to get out."

Kinako had no choice but to step aside.

But the resentment and anger in her eyes were clearly written on her face.

Suya has already seen the riddle.

This is an English version of Huarong Road.

Suya easily solved the problem with a few pushes.

The group arrived at the door of the second room.

This is an intelligence test question.

You tossed a coin 10 times, and each time it landed heads up. Now, assuming everything else is the same, what is the probability that the coin will land heads up on the 11th toss?

Suya filled in half.

If 40 bakers can bake 20 pies in two hours, how many hours would it take two bakers to bake 10 pies?

Suya wrote for 20 hours.

A snail wants to climb out of a well. The well is 20 feet deep. The snail climbs 3 feet each day and slides down 2 feet each night. How many days will it take the snail to climb out of the well?

Suya filled in 18 days

A pasture has a grassy area. If 27 cows are raised there, they will eat all the grass in 6 days; if 23 cows are raised there, they will eat all the grass in 9 days. If 21 cows are raised there, how many days will it take to eat all the grass in the pasture?

Suya filled in 12

Doorway to the seventh room

A group of people are having a dance party, and everyone is wearing a hat. The hats are either black or white, and there is at least one black hat. Everyone can see the color of everyone else's hat, but not their own. The emcee first lets everyone see what hats everyone else is wearing, then turns off the lights. If anyone thinks they are wearing a black hat, they are to slap themselves. The first time the lights are turned off, there is no sound. So the lights are turned back on, everyone looks again, and when the lights are turned off again, there is still complete silence. It's not until the third time the lights are turned off that the sound of slapping can be heard. How many people are wearing black hats?
