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(zhuān)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(xiāo)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(xiāo)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(xiāo)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(mài)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(lèi)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(xiāo)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(lèi)討論法例:某商場(chǎng)在進(jìn)行滿(mǎn)百省活動(dòng),滿(mǎn)100省10,滿(mǎn)200省30,滿(mǎn)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(mǎi)某款襯衫1件支付了175元,那么買(mǎi)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(mǎi)3件襯衫需要支付1853=555元400元,所以將555元滿(mǎn)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(mǎi)3件襯衫需要支付2053=615400元,所以將615元滿(mǎn)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(mǎi)其原料的顧客實(shí)行如下優(yōu)惠措施:①一次購(gòu)買(mǎi)金額不超過(guò)1萬(wàn)元,不予優(yōu)惠;②一次購(gòu)買(mǎi)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(mǎi)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(mǎi)原料付款7800元,第二次購(gòu)買(mǎi)付款26100元,如果他一次購(gòu)買(mǎi)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(mǎi)原料付款7800元,原料的總價(jià)值應(yīng)為7800元,第二次購(gòu)買(mǎi)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(mǎi)變成一次購(gòu)買(mǎi),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(mǎi)比分兩次購(gòu)買(mǎi)可以節(jié)約7800+26100-32440=1460元,選A。中公教育專(zhuān)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(lèi)題目的分?jǐn)?shù)拿到手中,最后祝大家一舉成功!
