Chapter 109 (1/2)

It's seven o'clock in the evening.

A full hour has passed since the test began.

However, according to the difficulty of the test, most of the students who participated in the test did not reach the tenth question.

Except, of course, some evil characters.

Qingcheng City, Zhuyuan district.

Cheng Nuo rubbed some sour eyes, moved his fingers and said with a smile, ”only the last ten questions are left!”

Yes, compared with other Xueba who are still hovering in more than ten questions, Cheng Nuo has come to question 41!

This is a basic two-point question.

2+3=13

3+4=25

4+5=41

5+6=？

The requirement of the title is to deduce the final ”5 + 6” equal to according to the law of the above three equations.

Cheng Nuo takes a look at it, and different numbers fly in his mind.

Suddenly, the corner of Cheng Nuo's mouth slowly rises. ”Is it Pythagorean theorem?”

Soon, Cheng Nuo will fill in the blanks - 61!

Next, reasoning questions, basic points 3 points!

The questions are as follows:

there are five persons a, B, C, D and E. Everyone wore a white or black hat on their heads. Everyone can see the color of the hat on other people's heads, but they can't see the color of their own.

If a person is wearing a white hat, he is telling the truth; if he is wearing a black hat, he is telling a lie. What they said was as follows:

a said: I saw three white hats and a black hat.

B: I see four black hats.

C: I see a white hat and three black hats.

E said: I see four white hats.

Q: what color are the hats each of them wears?

This is a very basic reasoning problem.

”It's another sub question.” Cheng Nuo shakes his head and chuckles. Fill in the answers at your fingertips.

Cheng Nuo presses the OK key to move on to the next question.

”In five seconds, the topic will appear, please be ready! At the end of the question, please fill in the blanks with the calculation results! ”

The screen displays a prompt with a countdown of five seconds next to it.

At the same time, many of the 100000 candidates did the same thing as Cheng Nuo.

They can't help but abandon their concentration and focus on the computer screen.

3！ 2！ 1！

A number appears on the computer screen: 651!

After a second, the first number disappears and the next number appears + 157!

After a second: - 541!

Next second: - 211!

…………

Every second, the previous number on the screen disappears and the next number appears.

All the players need to do is sum all the numbers on the screen. The result of making a peace is the final answer.

The test of this problem is the player's quick calculation and memory. To be precise, it's quick calculation or memory.

If you don't have enough memory, you can calculate the results quickly.

But if you can't count your speed, you can count all the numbers in your mind with a strong memory.

Cheng Nuo is not talented. He has both abilities.

On the number of memory and computing power, I am afraid only robots can do it.

-294！

+947！

Ten numbers, ten seconds, appear on the screen in turn.

When the last number ”+ 947” disappears under their noses, the minds of those who are doing this problem are like this:??? ”

Who am I? Where am i? What am I doing?
