小高分享（89）行测学习数量关系题

摘要：工程问题用"效率=总量/时间"，设总量为效率最小公倍数（如甲3天/乙5天设总量15）；经济利润牢记"利润率=（售价-成本）/成本"，遇到打折题直接设成本100元秒杀；和定最值题遵循"求最大其余最小"铁律，5人分2000元直接选600元（选项必有）。2024省考

Xiao Gao's Sharing (89): Learning Quantitative Relationship Questions in the Civil Service Examination

Welcome to your visit!

一、锁定高频题型、

First. Focus on high-frequency question types

工程问题用"效率=总量/时间"，设总量为效率最小公倍数（如甲3天/乙5天设总量15）；经济利润牢记"利润率=（售价-成本）/成本"，遇到打折题直接设成本100元秒杀；和定最值题遵循"求最大其余最小"铁律，5人分2000元直接选600元（选项必有）。2024省考数据显示，掌握这3类题型可稳拿12分。

Engineering problems can be solved using the formula "efficiency = total quantity / time". Let the total quantity be the least common multiple of the efficiencies (for example, if person A works 3 days and person B works 5 days, set the total quantity as 15); for economic profits, remember "profit rate = (selling price - cost) / cost". When encountering discount questions, directly set the cost as 100 yuan to quickly solve them. For problems involving fixed ratios and maximum/minimum values, follow the "find the maximum and the rest is the minimum" rule. For example, when dividing 2000 yuan among 5 people, directly choose 600 yuan (the options must include it). Data from the 2024 provincial examination shows that mastering these three types of questions can guarantee a score of 12 points.

二、黄金20分钟法则

Second. The 20-Minute Rule for Gold

前10题用50秒/题速攻基础题（工程/利润/最值），中间5题用80秒攻克中等题（行程/排列），后5题直接标记。遇到复杂行程题画线段图，排列组合题默念"元素不同选排列"，几何题优先试3-4-5勾股数。记住：选项带分数必考工程问题，带百分数必考利润率，带"最多/最少"必考最值。

The first 10 questions should be answered quickly in 50 seconds per question (covering topics such as engineering, profit, and extremum). The next 5 questions should be solved in 80 seconds (including problems related to motion and permutations). The last 5 questions should be marked directly. For complex motion problems, draw a line graph; for permutation and combination problems, mentally say "select permutations when elements are different". For geometric problems, try using the 3-4-5 Pythagorean triple first. Remember: problems involving fractions in the options are definitely about engineering; problems with percentages are definitely about profit; problems with "maximum/minimum" are definitely about extremum.

三、从公式到实战

Third. From Formula to Practice

D1-3：每天背20个核心公式（打印A4纸贴床头），刷50道基础题，建立"公式错/计算错/审题错"三本账；D4-5：全真模考训练标记题，掌握代入排除+数字特性组合技；D6-7：默写5大核心公式，下载最新命题趋势报告。

D1-3: Every day, memorize 20 core formulas (print on A4 paper and stick on the bedside); solve 50 basic questions; set up three accounts for "formula mistakes/ calculation mistakes/ reading comprehension mistakes"; D4-5: Full-scale mock exam training with marked questions, master substitution elimination + combination techniques based on number characteristics; D6-7: Memorize 5 major core formulas, download the latest proposition trend report.
