Daim npav dag no yog qhov zoo rau cov pib vim nws yuav tsum tsis muaj tes tuav tes ua haujlwm-tsuas yog lej yooj yim. Txawm tias tsis nkag siab txog kev ua lej li cas koj tseem tuaj yeem ua qhov "khawv koob" no kom ua rau txhua tus phooj ywg zoo siab!
Cov kauj ruam
Kauj Ruam 1. Muab koj tus phooj ywg faib ua nees nkaum ib daim npav ua si
Qhia lawv kom xaiv ib qho, yam tsis qhia lossis qhia koj tias daim npav twg lawv xaiv, thiab tso daim npav rov qab rau hauv pawg ntawm qhov xwm txheej.
Kauj Ruam 2. Deal daim npav tawm hauv peb kab, ua haujlwm ib-kab-kab (kab 1-kab 2-kab 3-kab, 1-2-3, 1-2-3, thiab lwm yam
). Koj yuav tsum muaj peb kab ntawm xya daim npav nyob ntawm koj xub ntiag. Kom koj tus phooj ywg qhia koj tias pawg twg muaj lawv daim npav (tsis tau qhia koj tias daim npav twg yog, ntawm chav kawm).
Kauj Ruam 3. Sib sau peb kab ntawv rau hauv ib pawg ntawm daim npav dua, nco ntsoov muab cov pawg uas tuav lawv daim npav nyob nruab nrab ntawm peb pawg
Piv txwv, yog thawj pawg muaj lawv daim npav, koj tuaj yeem khaws cov pawg thib peb ua ntej, tom qab ntawd pawg thawj (muaj daim npav) thiab tom qab ntawv pawg thib ob - lossis pawg thib ob, tom qab ntawd thawj, tom qab ntawd thib peb. Nws yog ib qho tseem ceeb heev uas pawg uas muaj lawv daim npav nkag mus rau hauv nruab nrab.
Kauj Ruam 4. Rov ua dua ob kauj ruam dhau los ob zaug ntxiv
Thaum ua tiav, koj yuav tau muab cov npav rho tawm tag nrho 3 zaug.
Kauj Ruam 5. Yog tias koj tau ua daim npav dag kom raug lawv daim npav yuav yog daim npav 11 hauv daim npav
Kauj Ruam 6. Koj tus phooj ywg xav tsis thoob yuav nug koj tias koj tau ua li cas
Koj tuaj yeem qhia lawv tias nws yog khawv koob … lossis koj tuaj yeem piav qhia qhov lej yooj yim uas ua rau nws ua haujlwm. Txhua lub sijhawm koj hais txog daim npav koj tab tom faib daim npav. Txog zaum thib 3 koj tau txais daim npav mus rau nruab nrab ntawm pawg. Yog li koj tuaj yeem qhia qhov twg lawv daim npav yuav nyob txhua lub sijhawm. Cov mis yog Y = (X + 1)/2, qhov twg X yog tus lej ntawm daim npav thiab Y yog qhov muab daim npav tso rau hauv pawg tom qab kev pom zoo thib 3. Hauv qhov no, txij li X yog 21, Y = 22/2 = 11.
Lub tswv yim
- Nov yog lwm txoj hauv kev los xaus qhov kev dag no: cia koj tus phooj ywg "nrhiav" daim npav xaiv. Thaum koj paub daim npav thib kaum yog qhov raug, koj npaj txhua daim npav, ntsej muag, hauv plaub pawg, 1-2-3-4, 1-2-3-4, thiab lwm yam. Vim tias koj muaj 21 daim npav, pawg 1 yuav xaus nrog rau daim npav, thiab pawg 2, 3, thiab 4 nrog tsib txhua. Yog tias koj tau ua raws cov txheej txheem no, daim npav raug yuav tsum yog daim npav nruab nrab hauv pawg 3. Tam sim no muab ib txhais tes hla cov pawg 1 thiab 2 thiab lwm tes hla pawg 3 thiab 4, nug koj tus phooj ywg: "Koj xaiv qhov twg, ob qho no los yog ob qho no? " Txij li txhua daim npav poob ntsej muag, koj tus phooj ywg tsis muaj txoj hauv kev paub qhov twg yog daim npav raug thiab yog li ntawd tsuas yog tuaj yeem xaiv ua ke. Xijpeem lawv xaiv, tshem tawm pawg 1 thiab 2. (Yog tias koj ua qhov no sai, nws ua haujlwm. Yog tias lawv xaiv 1 thiab 2, koj tsuas yog tshem tawm qhov lawv taw tes rau; yog tias lawv xaiv 3 thiab 4, koj ua rau nws zoo li lawv tau xaiv khaws cov ntawd los ntawm kev tshem 1 thiab 2.) Tam sim no muab ib txhais tes hla pawg 3 thiab ib qho hla pawg 4 thiab nug lawv tib lo lus nug. Tshem tawm pawg 4. Tam sim no faib pawg 3 ua ob pawg, ib qho nrog 3 thiab lwm qhov nrog 2 daim npav. (Xyuas kom koj paub tias daim npav raug tsaws nyob qhov twg.) Ua qhov no, tshem tawm cov pawg uas tsis suav nrog daim npav raug, kom txog thaum tsuas muaj ib daim npav tso rau ntawm lub rooj, tseem ntsej muag. Nug koj tus phooj ywg kom muab nws xa rov qab. Qhov tseeb tias lawv "pom" daim npav raug lawm yeej tsis tso tseg li ua rau lawv xav tsis thoob.
- Lwm txoj hauv kev los xaus qhov kev dag no tuaj yeem yeej thawj koom ruam txhua lub sijhawm. Thaum koj muaj txhua yam teeb tsa kom daim npav thib kaum yog lawv daim npav, faib tawm 13 daim npav ntsej muag ua ke, tsis yog pawg. Ua tib zoo saib qhov twg yog nqe 11. Tam sim no hais rau tus neeg, "Kuv yuav twv koj daim npav tom ntej uas kuv tig hla yog koj li." Cov lus no tseem ceeb heev. Thaum lawv lees txais qhov thawj koom ruam, uas lawv yuav vim lawv paub daim npav tom ntej hauv lub lawj ntawv tsis yog lawv li, thiab lawv raug lawm; koj nyob ntsiag to tuav daim npav thib kaum uas koj tau ntxeev thiab tig nws lub ntsej muag, yog li daim npav tom ntej koj tig yog lawv li.
- Koj tuaj yeem hloov qhov kev dag no los ntawm kev siv pawg sib txawv sib txawv, tsuav tus lej ntawm daim npav muaj ntau ntawm 3 (3, 6, 9, 12, 15, 18, 21, 24, 27, 30, thiab lwm yam). Nco tseg: yog tias muaj pes tsawg daim npav, qhov ua kom yuam kev txawv me ntsis: Tsis txhob muab cov pawg tso rau hauv nruab nrab txhua lub sijhawm, koj yuav tsum muab cov pawg tso rau saum toj thawj zaug thiab nyob hauv nruab nrab ob seem ntxiv. Hauv qhov xwm txheej ntawd qhov sib npaug cuam tshuam yog Y = X/2 qhov twg, ntxiv, X yog tus lej ntawm daim npav thiab Y yog qhov muab daim npav tso rau hauv pawg tom qab kev pom zoo thib 3. Nrog cov ntaub ntawv no koj tuaj yeem ua rau koj cov phooj ywg zoo dua ntxiv los ntawm kev siv tus lej sib txawv ntawm daim npav txhua lub sijhawm.
