2018遼寧軍隊(duì)文職招考考試軍隊(duì)文職崗位能力技巧：利潤(rùn)問(wèn)題常用方法
在每年的考試當(dāng)中，利潤(rùn)問(wèn)題作為?？碱}型，所占比重越來(lái)越大，然而在計(jì)算的時(shí)候，比較浪費(fèi)時(shí)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(shè)為特值，常設(shè)為1或100。例：去年10月份一臺(tái)電腦的利潤(rùn)率為50%，11月份降價(jià)10%，后在12月份價(jià)格又上漲5%，問(wèn)12月份該電腦的利潤(rùn)率為多少?紅師解析：設(shè)電腦的成本為100，則10月份訪電腦的售價(jià)為100(1+50%)=150，則12月份該電腦的價(jià)格為150(1-10%)(1+5%)=，因此12月份電腦的利潤(rùn)率=。二、比例法：根據(jù)公式售價(jià)=成本(1+利潤(rùn)率)，當(dāng)售價(jià)一定時(shí)，成本與(1+利潤(rùn)率)成反比。例：某商品第二次進(jìn)價(jià)是第一次進(jìn)價(jià)的80%，若售價(jià)不變，則利潤(rùn)率比第一次銷售此商品時(shí)的利潤(rùn)率高30個(gè)百分點(diǎn)，問(wèn)第一次銷售此商品時(shí)所定的利潤(rùn)率是多少?紅師解析：兩次進(jìn)價(jià)之比=5：4，而售價(jià)不變，則兩次(1+利潤(rùn)率)之比=4：5，設(shè)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(shí)所定的利潤(rùn)率為20%。三、方程法：關(guān)鍵是找到等量關(guān)系。例：某商品按20%利潤(rùn)定價(jià)，然后按8.8折賣出，共獲得利潤(rùn)84元，求商品的成本是多少元?紅師解析：設(shè)成本是x元，根據(jù)利潤(rùn)=售價(jià)-成本列方程，則有x(1+20%)=84，解得x=1500。四、十字交叉法：利潤(rùn)率的混合問(wèn)題，類似于濃度混合問(wèn)題。例：一批商品，按期望獲得50%的利潤(rùn)來(lái)定價(jià)。結(jié)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(jià)打折銷售，這樣所獲得的全部利潤(rùn)是原來(lái)的期望利潤(rùn)的82%，問(wèn)打了幾折?A.7C.8紅師解析：設(shè)打折后的利潤(rùn)率為x%，應(yīng)用十字交叉法，得：五、分類討論法例：某商場(chǎng)在進(jìn)行滿百省活動(dòng)，滿100省10，滿200省30，滿300省50。大于400的消費(fèi)只能折算為等同于幾個(gè)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(jià)是175+10=185元或175+30=205元。當(dāng)原價(jià)為185元時(shí)，未參加活動(dòng)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(dāng)原價(jià)為205元時(shí)，未參加活動(dòng)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(gè)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(jì)價(jià)法例：某原料供應(yīng)商對(duì)購(gòu)買其原料的顧客實(shí)行如下優(yōu)惠措施：①一次購(gòu)買金額不超過(guò)1萬(wàn)元，不予優(yōu)惠;②一次購(gòu)買金額超過(guò)1萬(wàn)元，但不超過(guò)3萬(wàn)元，給九折優(yōu)惠;③一次購(gòu)買金額超過(guò)3萬(wàn)元，其中3萬(wàn)元九折優(yōu)惠，超過(guò)3萬(wàn)元部分八折優(yōu)惠。某廠因庫(kù)容原因，第一次在該供應(yīng)商處購(gòu)買原料付款7800元，第二次購(gòu)買付款26100元，如果他一次購(gòu)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(gòu)買原料付款7800元，原料的總價(jià)值應(yīng)為7800元，第二次購(gòu)買時(shí)付款26100元，原料的總價(jià)值應(yīng)為26100元。如果要將兩次購(gòu)買變成一次購(gòu)買，則總價(jià)值應(yīng)為7800+29000=36800元，而應(yīng)該付款額為30000元，一次性購(gòu)買比分兩次購(gòu)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(guò)此種方法的學(xué)習(xí)，可以快速有效地解決利潤(rùn)問(wèn)題的題目，把這類題目的分?jǐn)?shù)拿到手中，最后祝大家一舉成功!
