20、10 名同学参加数学竞赛,前4 名同学平均得分 150 分,后 6名同学平均得分比10 人的平均分少 20分,这 10 名同学的平均分是 _分.2、某商店想进饼干和巧克力共444 千克,后又调整了进货量,使饼干增加了20 千克,巧克力减少 5%,结果总数增加了7 千克。那么实际进饼干多少千克?3、某文具店用 16000 元购进 4 种练习本共 6400本。每本的单价是:甲种4 元,乙种 3 元,丙种 2 元,丁种 14 元。如果甲、丙两种本数相同,乙、丁两种本数也相同,那么丁种练习本共买了 _本。4、六年级某班学生中有161的学生年龄为 13 岁,有43的学生年龄为12 岁,其余学生年龄为11

21、 岁,这个班学生的平均年龄是_岁。5、某个五位数加上20 万并且 3 倍以后,其结果正好与该五位数的右端增加一个数字2 的得数相等,这个五位数是 _。6、大小酒桶共80 个,每个大桶可装酒25 千克,每个小桶可装酒15 千克,大桶比小桶共多装 600 千克,则大酒桶有 _个。7、某自来水公司水费计算办法如下:若每户每月用水不超过5 立方米,则每立方米收费1.5元,若每户每月用水超过5 立方米,则超出部分每立方米收取较高的定额费用,1 月份,张家用水量是李家用水量的32,张家当月水费是17.5 元,李家当月水费27.5 元,超出 5 立方米的部分每立方米收费多少元?8、某县农机厂金工车间有77个

22、工人.已知每个工人平均每天可以加工甲种零件5 个或乙种零件 4 个,或丙种零件3 个。但加工 3 个甲种零件,1 个乙种零件和 9 个丙种零件才恰好配成一套.问:应安排生产甲、乙、丙种零件各多少人时,才能使生产的三种零件恰好配套?典型应用题精练(列方程解应用题)参考答案1、【解】:设 10人的平均分为 a 分,这样后 6 名同学的平均分为 a-20 分,所以列方程:10a-6(a-20)4=150 解得:a=120。2、【解】:设饼干为 a,则巧克力为 444-a,列方程:a+20+(444-a)(1+5%)-444=7 解得:a=184。3、【解】:设甲、丙数目各为a,那么乙、丁数目为,所以

23、列方程4a+3+2a+14=16000 解得:a=1200。4、【解】:因为是填空题,所以我们直接设这个班有16 人,计算比较快。所以题目变成了:1 个学生年龄为 13 岁,有 12 个学生年龄为 12 岁,3 个学生学生年龄为11 岁,求平均年龄?(131+1212+113)1611.875,即平均年龄为 11.875 岁。如果是需要写过程的解答题,则可以设这个班的人数为a,则平均年龄为:11.875。名师资料总结-精品资料欢迎下载-名师精心整理-第 1 页,共 7 页 -Learn General Secretary on two to learn a strengthening four

43、(80 x)600,解得 x45 个。方法二:鸡兔同笼,假设全是大桶,这样就是 0 个小桶,这样大桶比小桶多装8025=2000千克,而现在只有多装了600 千克,所以多 2000-600=1400 千克,每个大桶变成小桶大桶比小桶多装的就减少25+15=40千克,所以有 140040=35个小桶,所以大桶的数目为45 个。7、【解】:设出 5 立方米的部分每立方米收费X,(17.5-5 1.5)X+5=(27.5-5 1.5)X+5(2/3)解得:X=2。8、分析 如果直接设生产甲、乙、丙三种零件的人数分别为x 人、y 人、z 人,根据共有 77 人的条件可以列出方程x+yz=77,但解起来

44、比较麻烦。如果仔细分析题意,会发现除了上面提到的加工甲、乙、丙三种零件的人数这三个未知数外,还有甲、乙、丙三种零件的各自的总件数.而题目中又有关于甲、乙、丙三种零件之间装配时的内在联系,这个内在联系可以用比例关系表示,而乙种零件件数又在中间起媒介作用.所以如用间接未知数,设乙种零件总数为 x 个,为了配套,甲种、丙种零件件数总数分别为3x 个和 9x 个,再根据生产某种零件人数=生产这种零件的个数工人劳动效率,可以分别求出生产甲、乙、丙种零件需安排的人数,从而找出等量关系,即按均衡生产推算的总人数=总人数,列出方程。解:设加工乙种零件x 个,则加工甲种零件3x 个,加工丙种零件9x 个。例 1

45、、有两种不同浓度的盐水,甲种盐水的浓度是30%,乙种盐水的浓度是6%,现在要配成浓度为 10%的盐水 60千克,问应取这两种浓度的盐水各多少千克?设应取甲种盐水x 千克,那么乙种盐水应取(60-x)千克,甲种盐水中含盐30%x千克,乙种盐水中含盐 6%(60-x)千克,根据题意,得答:甲种浓度盐水取 10 千克,乙种浓度盐水取50 千克。例 2、一件工作,甲单独做需20 小时完成,乙单独做需12小时完成,现在先由甲单独做4小时,剩下的部分由甲、乙合作,剩下的部分需几小时完成?思路导航:此题属于工程问题,可把总工作量看作1,甲单独做 4 小时的工作量和甲、乙合作的工作量之和就等于总工作量“1”。

46、解答:设剩下的部分甲、乙合作需x 小时完成,则甲单独做4小时的工作量名师资料总结-精品资料欢迎下载-名师精心整理-第 2 页,共 7 页 -Learn General Secretary on two to learn a strengthening four Consciousnesses important speech caused a strong reaction i n the country.me,watching red treasure,the origin of building the party back to power,how to strengthen servi
