The subjects of civil service examination (national examination and provincial examination) include two parts: line test and application.
The bank mainly examines your knowledge, analytical ability, calculation ability and logical thinking ability. , generally divided into five types. Application is an inspection of your actual ability to analyze and solve problems according to the needs of state organs, which is generally current affairs and political materials.
Generally speaking, the line side can be divided into the following five categories: speech comprehension, quantitative relations (including numerical reasoning and mathematical operations), judgment reasoning (including graphic reasoning, definition judgment, event sequencing and deductive reasoning), common sense judgment and data analysis.
"Shen Lun" is an examination subject to examine the basic ability that an organ should have in its work. The thesis consists of three parts: matters needing attention, given information and answering requirements. According to the different requirements of comprehensive management at or above the provincial level (including sub-provincial level), comprehensive management below the city (prefecture) and administrative law enforcement posts, two types of papers are set up for the application examination.
Examples of quantitative relationship in "line test"
20 people can finish a job in 15 days. Now working for three days, five people are transferred to plant trees, and the rest continue to finish the rest of the work. How many days will it take to finish the work?
16, 17, 18, 19
General solution. The first type: special value method. Assume that the workload per person per day is 1, the total workload is 20× 15× 1=300, the amount completed first is 20× 3×1= 60, and the remaining 300-60=240, which requires 240 ?.
The second type: proportional method. The efficiency ratio before and after 3 days =20: 15=4:3, then the time ratio =3:4, then the later workload is 12 days according to the original efficiency, that is, 3 copies correspond to 12 days, then 4 copies correspond to 16 days, and * * is counted as/
"The second kill in a row": (20 *15-3 *15)/(20-5)+3 =19 days. Option A is the time required for others to finish the work, but it is not the desired result. However, it is easy for candidates to choose the wrong A in the examination room (A is actually a trap set by the questioner) and D is "How many days does it take to finish the homework?" .
