2018遼寧軍隊文職招考考試軍隊文職崗位能力技巧:利潤問題常用方法
在每年的考試當中,利潤問題作為常考題型,所占比重越來越大,然而在計算的時候,比較浪費時間,今天專家把這一部分題技巧給大家梳理一下。一、特值法:一般情況下,把未知量成本設為特值,常設為1或100。例:去年10月份一臺電腦的利潤率為50%,11月份降價10%,后在12月份價格又上漲5%,問12月份該電腦的利潤率為多少?紅師解析:設電腦的成本為100,則10月份訪電腦的售價為100(1+50%)=150,則12月份該電腦的價格為150(1-10%)(1+5%)=,因此12月份電腦的利潤率=。二、比例法:根據(jù)公式售價=成本(1+利潤率),當售價一定時,成本與(1+利潤率)成反比。例:某商品第二次進價是第一次進價的80%,若售價不變,則利潤率比第一次銷售此商品時的利潤率高30個百分點,問第一次銷售此商品時所定的利潤率是多少?紅師解析:兩次進價之比=5:4,而售價不變,則兩次(1+利潤率)之比=4:5,設所求為x,則(1+x):(1+x+30%)=4:5,,解得x=0.2,即第一次銷售此商品時所定的利潤率為20%。三、方程法:關鍵是找到等量關系。例:某商品按20%利潤定價,然后按8.8折賣出,共獲得利潤84元,求商品的成本是多少元?紅師解析:設成本是x元,根據(jù)利潤=售價-成本列方程,則有x(1+20%)=84,解得x=1500。四、十字交叉法:利潤率的混合問題,類似于濃度混合問題。例:一批商品,按期望獲得50%的利潤來定價。結果只售出70%的商品,為盡早售完剩下的商品,商店決定按定價打折銷售,這樣所獲得的全部利潤是原來的期望利潤的82%,問打了幾折?A.7C.8紅師解析:設打折后的利潤率為x%,應用十字交叉法,得:五、分類討論法例:某商場在進行滿百省活動,滿100省10,滿200省30,滿300省50。大于400的消費只能折算為等同于幾個100、200、300的加和。已知一位顧客買某款襯衫1件支付了175元,那么買3件這樣的襯衫最少需要()。元元元元紅師解析:由題意知這款襯衫原價是175+10=185元或175+30=205元。當原價為185元時,未參加活動之前買3件襯衫需要支付1853=555元400元,所以將555元滿百的部分折算為200、300的加和,共省30+50=80元,故最少需要支付555-80=475元。當原價為205元時,未參加活動之前買3件襯衫需要支付2053=615400元,所以將615元滿百的部分折算為兩個300的加和,共省50+50=100元,故最少需要支付615-100=515元475元。故所求為475元,選B。六、分段計價法例:某原料供應商對購買其原料的顧客實行如下優(yōu)惠措施:①一次購買金額不超過1萬元,不予優(yōu)惠;②一次購買金額超過1萬元,但不超過3萬元,給九折優(yōu)惠;③一次購買金額超過3萬元,其中3萬元九折優(yōu)惠,超過3萬元部分八折優(yōu)惠。某廠因庫容原因,第一次在該供應商處購買原料付款7800元,第二次購買付款26100元,如果他一次購買同樣數(shù)量的原料,可以少付()。元元元元紅師解析:第一次購買原料付款7800元,原料的總價值應為7800元,第二次購買時付款26100元,原料的總價值應為26100元。如果要將兩次購買變成一次購買,則總價值應為7800+29000=36800元,而應該付款額為30000元,一次性購買比分兩次購買可以節(jié)約7800+26100-32440=1460元,選A。中公教育專家希望廣大考生通過此種方法的學習,可以快速有效地解決利潤問題的題目,把這類題目的分數(shù)拿到手中,最后祝大家一舉成功!
2018寧夏軍隊文職招考考試軍隊文職人員招聘公共基礎寫作熱點:全民閱讀
|背景鏈接*黨的十八大報告歷史性地寫入開展全民閱讀活動,標志著全民閱讀已經(jīng)成為黨中央的一項重要戰(zhàn)略部署。開展全民閱讀活動是我國構建公共文化服務體系的一項重要部署,對培育和踐行社會主義核心價值觀,提高國民思想道德素質和科學文化素質,建設社會主義文化強國,增強國家文化軟實力,實現(xiàn)中華民族偉大復興中國夢具有重要意義。|公考角度中公解讀*[存在問題]1.低頭族不斷壯大,現(xiàn)在越來越多的國民把自己的業(yè)余生活消耗在網(wǎng)絡上。2.國民對于信息過載缺乏理性的選擇。電腦和網(wǎng)絡顛覆了傳統(tǒng)紙質閱讀習慣,越來越多人喜歡利用電腦閱讀,而電腦中少量的信息則充斥著熒屏,使國人閱讀生活呈浮躁化,支離破碎化,令人擔憂。3.國民閱讀態(tài)度有待改進。目前存在的相當一部分目標讀者和功利讀者,與文字只有泛泛之交,按自己所需下載所求信息,在閱讀中缺乏理性的思索,精神世界與文化素養(yǎng)必將匱乏,閱讀的價值與美感也必將消失殆盡。4.未成年人閱讀狀況不容樂觀。只注重分數(shù)的提升,舍不得花時間認真閱讀,是閱讀收到排擠,閱讀視野狹窄化,讀書的功利性與實用性在學生中泛濫成災。5.國家對于全民閱讀的主導推動作用與保健措施不到位。國家閱讀公共資源和設施不足,布局不平衡。對于國民閱讀的良莠不齊,缺乏積極引導、扶持,沒有出臺完善的優(yōu)秀書目推介工程,全民閱讀缺乏統(tǒng)一規(guī)劃,組織保障和經(jīng)費支持。[提出問題]1.圍繞中心開展各種形式的主題讀書活動2.充分發(fā)揮優(yōu)秀出版物的引領作用3.培育鞏固一批書香中國活動品牌4.面向基層開展全民閱讀七進活動5.加強全民閱讀公共服務體系建設6.繼續(xù)推動全民閱讀立法和規(guī)劃工作7.努力營造書香中國濃厚氛圍8.加強對全民閱讀的組織協(xié)調
