Written examination questions for recruitment of CCB

CCB's written experience in spring recruitment and three problem-solving skills in line testing.

The written examination time of spring campus recruitment of CCB is May 2020 10, 14: 00- 17: 00. 1 day from now. Students should hurry up and sprint before the exam, and their written test scores can be further improved.

Share with you some problem-solving skills in the line test. Each skill is illustrated by matching real questions. Flexible use, you will know the answer when you see the question in the written test, which greatly improves the speed of doing the question.

I. Separability

Divisibility is often used in solving the problem of quantitative relations, mainly for fast calculation. Combined with the characteristics of public examination number calculation, divisibility is more a kind of thinking than a method. According to the options, there is no need to calculate. Division with remainder can be combined here, and the theoretical basis is congruence problem and residue theorem.

There are 80% more boys than girls in a class. In one exam, the average class score is 75, and the average score of girls is 20% higher than that of boys. So the average score of girls in this class is:

A, 84 points B, 85 points C, 86 points D, 87 points

Analysis: There are many ways to solve this problem, including the conventional equation method and the slightly better cross method, but these are not the divisibility of the numbers to be expressed here. Because "the average score of girls is 20% higher than that of boys", that is, the average score of girls is 1.2 times that of boys. In general, the score will only be an integer, so we only need to find the integer multiple of 12 in the option, and only 84 meets the problem.

To understand the characteristics of the exam, our purpose is to choose the correct answer, not to work it out by "strength" in a safe way, because the idea of the questioner is not for you to work out, and because of the time limit of the bank exam, you don't have time to work out the answer completely by calculation.

Second, mantissa

Mantissa is also a commonly used method in public examination arithmetic, and can also be used in data analysis to save valuable time for everyone.

Example: Xiaohua is practicing the summation of natural numbers, counting from 1 He found himself counting a number repeatedly. In this case, he averaged all the figures and the result was 7.4. What number did he repeat?

A.2 B.6 C.8 D. 10

Analysis: According to the characteristics of the summation formula of natural numbers, the average is the middle number. We can know that the number of terms in this series is greater than 13, which may be 14, 15 or 16, because the sum of natural numbers must be an integer. If it is 14 or 16, the decimal point appears in the mantissa of the total. After determining that the term is 15, considering that the sum of natural numbers is averaged, either integer or mantissa is 0.5, the mantissa of 7.4 must be generated by dividing the majority by 15, and 0.4* 15=6, so the extra number is 6.

Third, odd and even numbers.

The theoretical basis is that odd addition and subtraction is odd = even, even addition and subtraction is even, and odd addition and subtraction is odd.

For example, there are 50 true or false questions in an exam, and you will get 3 points for each correct answer. Don't do it or do it wrong, 1 point, 82 points for a student. What is the difference between the correct number of questions and the wrong number of questions (including not doing it)?

17 D. 16

Analysis: It is also very simple to do this problem with the method of chicken and rabbit problem, but there must be a special and better method for the problem involving digital characteristics. Right question+wrong question =50, which is even, so the difference between right question and wrong question should also be even, so choose D.

There are 23 problem-solving skills in the test. For more tips, please leave a message in the comments section.

In addition, it is suggested that students brush the "CCB real question simulation paper" at the same time, test by themselves, find out the weak items, and then solve the problems in a targeted manner. "CCB's characteristic knowledge" should also be viewed in reverse, so that you can get points directly when you encounter bank characteristics and common sense questions.
