Cov hauj lwm zoo ntawm ib qho kev lag luam yog tsis yooj yim sua yam tsis muaj kev npaj. Thaum kos daim phiaj phiaj xwm rau kev tsim cov khoom lag luam lossis cov kev pabcuam, koj yuav tsum paub tus nqi zoo li tus qauv teev. Hauv qhov tseeb, cov qauv teev yog cov qauv ib ntus rau kev ua haujlwm ntawm ib qho kev ua haujlwm tshwj xeeb thiab nthuav qhia nws qhov kev siv zog thiab, thaum kawg, muaj qhov cuam tshuam ncaj qha rau tus nqi ntawm cov khoom lossis cov kev pabcuam. Koj tuaj yeem xam nws koj tus kheej.
Cov Lus Qhia
Kauj ruam 1
Cov xuab moos tag nrho ntawm cov sijhawm ua haujlwm yog sib npaug nrog cov lej ntawm cov neeg ua haujlwm ntawm cov neeg ua haujlwm nyob rau hauv kev tsim khoom, sib npaug los ntawm lub sijhawm uas tau siv rau kev tsim khoom los ntawm kev sib koom tes ntawm cov neeg ua haujlwm no. Nws yuav tsis muaj qhov sib npaug nrog cov xuab moos uas tau siv tiag tiag, uas tuaj yeem ua tus qauv. Qhov no yog vim muaj qhov tseeb tias thaum lub sijhawm txheej txheem ntau lawm, txhua feeb ntawm lub sijhawm ua haujlwm tsis siv nrog kev sib txig sib luag.

Thov nco ntsoov tias qee lub sijhawm tau siv rau lub sijhawm so. Piv txwv tias koj tau suav cov sijhawm teev rau ib chav tsim khoom uas ua haujlwm 10 tus neeg rau 1 lub lis piam rau tag nrho 40 teev. Thaum nruab hnub, lawv siv sijhawm so 10 feeb ib zaug. Yog li, tag nrho lub sijhawm uas 10 tus neeg ua haujlwm siv sijhawm so thaum lub sijhawm tsib hnub ua haujlwm yuav yog:
(10 feeb * 2 * 5 hnub) * 10 tus neeg = 1000 feeb lossis 16, 7 teev.
Yog li ntawd, coj mus rau hauv tus account lub sijhawm siv ntawm lub sijhawm so, tag nrho lub sijhawm rau kev tsim khoom yog:
10 * 40 teev - 16, 7 = 383 teev.

Txhawm rau ua rau koj cov kev suav tau tseeb dua, lawv yuav tsum coj mus rau hauv cov hnub ntawm kev tsis taus ib ntus thiab tsis tuaj kawm ntawv. Daim duab no tuaj yeem hloov pauv raws li lub caij thiab hnub so poob rau ntawm ntau lub sijhawm. Raws li kev xyaum qhia, nyob rau nruab nrab rau xyoo nws yog 4%. Ua kom zoo dua cov nuj nqis suav nrog tus lej no, tus naj npawb ntawm tus txiv neej-teev yuav muab sib npaug rau:
383 - (383 * 0.04) = 367.7 txiv neej-teev.

Qhov ntsuas no tseem yog theoretical thiab yuav tsum tau hais kom meej meej, txij li kev ua haujlwm muaj zog nyob rau ib hnub ua haujlwm tseem sib txawv. Thaum pib ntawm hnub, cov neeg ua haujlwm xav tau sijhawm los npaj kev ua haujlwm, thiab thaum kawg npaj tau mus tsev. Tsis tas li ntawd, qee lub sijhawm tuaj yeem ploj vim tias tsis muaj cov khoom tsim nyog, cov khoom siv tawg. Cov kev poob zoo feem ntau tsis suav nrog ntau dua 7% ntawm lub sijhawm ua haujlwm. Nrog rau qhov no hauv siab, qhov muaj pes tsawg tus txiv neej-teev yuav yog:
367, 7 - (0, 07 * 367, 7) = 367, 7 - 27, 7 = 342 tus txiv neej-teev muaj kev xyaum.

Tam sim no laij koj cov xuab moos qub. Yog hais tias qhov kev ua haujlwm tau zoo ntawm pawg neeg ua haujlwm no tsis dhau qhov kev cai thiab sib npaug 100%, tom qab ntawd tus naj npawb ntawm cov xuab moos cov qauv yuav yog 342, yog tias lub zog ua haujlwm hauv pab pawg no nce siab dua thiab sib npaug 110%, ces koj yuav muaj 342 * 1, 10 = 376, 2 tus qauv -our.
Kauj Ruam 6
Los ntawm cov kev suav no, koj tuaj yeem pom tau tias yog pawg no tau muab daim ntawv tso cai ua haujlwm, lub sijhawm kwv yees kwv yees uas yog 400 teev, tom qab ntawd cov neeg ua haujlwm yuav tsis muaj sijhawm los ua kom tiav nws nyob hauv ib lub lim tiam. Xav txog qhov no thiab daws qhov teeb meem los ntawm kev nce tus naj npawb ntawm cov neeg ua haujlwm lossis hloov qee qhov ntawm xaj mus rau lwm ceg.
