There are two kinds of problems about quantitative relations.
The first question type: numerical reasoning. Each question is given a series, but one is missing. Candidates are required to carefully observe the relationship between the numbers in this series, find out the arrangement law, and then choose the most suitable and reasonable one from the four alternative answers to fill in the blanks, so as to make it conform to the arrangement law of the original series.
Necessary knowledge of digital reasoning: familiar with arithmetic progression, geometric progression, summation series, product series, power series, combination series, fraction series, prime number series, composite series, radical series, Nine palace map and so on.
The second question type: mathematical operation
Each question is given an arithmetic formula, or a paragraph expressing the quantitative relationship. Candidates are required to skillfully use basic arithmetic rules such as addition, subtraction, multiplication and division, and use basic mathematical knowledge to calculate the results accurately and quickly.
Necessary knowledge of mathematical operation: four operations, basic problem matching skills, basic operations, common quick calculation methods, distance problems, engineering problems, chicken and rabbit in the same cage, tree planting problems, square matrix problems, concentration problems, proportion problems, cattle and animal husbandry problems, permutation and combination problems, probability problems, income problems, set problems, geometry problems, segmentation problems, etc.
Part III: Judgment and reasoning.
It mainly tests the analysis and reasoning ability of candidates on various things, involving the understanding, comparison, combination, deduction and induction of graphics, text concepts, relationship between things and text materials.
There are four types of questions in this part.
The first question type: graphic reasoning. One or two groups of figures are given for each question, and candidates are required to observe carefully, find out the law of figure arrangement and choose the one that conforms to the law.
Key points of graphic reasoning: four basic test points: prime number, number, shape and position.
Specifically, it is-element change, quantity change, stroke type, superposition type, similarity, difference, regional change, movement type, Nine palace map, spatial reduction, parity check, rotation, translation and so on.
The second question type: definition judgment. Each question first gives a definition of a concept, and then lists four situations respectively, asking candidates to choose an answer that best meets or least meets the definition according to the definition.
Definition and judgment can be solved by the methods of "genus" and "species difference"
The third question type: analogical reasoning. Give a pair of related words, and then ask the candidates to find a pair of words with the closest or similar logical relationship from the alternative answers.
Analogical reasoning is solved by "making sentences"
The fourth question type: logical judgment. Give a statement for each question. The hypothesis is correct and beyond doubt. Candidates are required to choose the most appropriate answer according to this statement, which should be consistent with the given statement and can be directly deduced from the statement without any additional explanation.
You can use normal life logic to make logical judgments.
Laws of logical judgment: support and opposition (strengthening and weakening), induction (deduction), hypothesis (premise), explanation, evaluation, logical application, etc.
Part IV: Data analysis.
It mainly tests candidates' comprehensive understanding, analysis and processing ability of various forms of text, graphics, tables and other materials. This part usually consists of data, statistical charts, charts and written materials.
Generally speaking, a message has 3-5 questions. Candidates need to analyze, compare and calculate according to the information provided in the materials, and choose the answer that meets the meaning of the question from the four alternative answers.
This part of the survey appears in the form of words and charts. In recent years, there have been many comprehensive examinations, which are the combination of pictures, tables and words.
The key to solving this sub-topic is: speed! So you have to have good skills.
