1, the preferred interview topic for multinational famous enterprises

Now Xiaoming's family has crossed a bridge. It's dark when crossing the bridge, so there must be a light. Now it takes 1 second for Xiaoming to cross the bridge, 3 seconds for Xiaoming's brother, 6 seconds for Xiaoming's father, 8 seconds for Xiaoming's mother and 12 seconds for Xiaoming's grandfather. At most two people can cross the bridge at a time. The speed of crossing the bridge depends on the slowest one. The light turns on for 30 seconds and then goes out. Ask Xiaoming how to cross the bridge.

Let you do the first two big arithmetic problems.

Four couples sit together and chat. Of the four women, Xiaoli ate three pears, Xiaoyu ate two, Xiao Fang ate four and Xiaolian ate 1. Among these four people, Guoqiang eats as many pears as his wife, Xiangyang twice, Zhong Min three times and Wen Jia four times. They ate 32 pears together. Do you know who Zhong Min's wife is? Explain why. Do not be blind.

3. Interesting mathematical problems in ancient India

Ancient India also had a splendid culture like ancient China. The following is an interesting math problem in ancient Indian manuscripts.

There is a large swarm of bees, one fifth of which falls on azaleas and one third on gardenias. The difference between the two flew to the rose, and finally a little bee flew between the fragrant jasmine and magnolia. How many bees are there?

4. Apple IQ test

There are ten baskets of apples, each basket has ten apples, *** 100 apples. The apples in each basket weigh the same, of which 9 baskets weigh 1 kg, and the apples in the other basket weigh 0.9 kg, but the appearance is exactly the same, which can't be distinguished by eyes or hands. Now I want you to find the light basket at once with an ordinary big scale. Can you do it?

5. Primary challenges of Olympic mathematics in primary schools

Number the boxes, then take out an apple from the first box, two apples from the second box, three apples from the third box, and so on. Weigh all the apples taken out together. Less than 0. 1 indicates that the apples in the first box are light, less than 0.2 indicates that the apples in the second box are light, less than 0.3 indicates that the apples in the third box are light, and so on.

IQ is not equal to intelligence, let alone achievement.

Intelligent testing has advantages and disadvantages. The IQ score is just a data point, which has obvious limitations. Memory test, attention test, executive function test, previous education level, academic performance, pre-illness function test, etc. , each representing a data point. Only by putting many data points together can we have a more comprehensive understanding of a person's intelligence level. How to understand these data points requires psychologists to sort out according to the knowledge they have learned and the background of the subjects.
