Muzvinafundo Shane Frederick weMassachusetts Institute of Technology akagadzira ipfupi IQ bvunzo ine mibvunzo mitatu chete.

Maererano nepepanhau girazi MaBritish, kuti bvunzo iyi yakaumbwa muna 2005 kuona kugona kwekuziva, uye ikozvino yaburitswa muInternet.

Mibvunzo inosanganisirwa muyedzo

1- Racket uye tenesi bhora zvakakosha $ 1.10 pamwechete. Uye raki rinodhura kupfuura bhora nedhora rimwe chete.

Bhora rakawanda zvakadii?

2- Makina mashanu mufekitori yemachira anoburitsa zvidimbu zvishanu mumaminitsi mashanu.

Zvinotora maminetsi mangani kuburitsa zvidimbu zana?

3- Dzinokura mudziva remaruva emvura. Iko zuva rega rega nhamba yavo inopetwa kaviri, uye zvinozivikanwa kuti maruva aya anogona kuvhara pamusoro pegungwa mukati memazuva makumi mana nemasere.

Mazuva mangani maruva anoda kuvhara hafu yedziva?

Iko purofesa akaitisa kuyedza uko vangangoita zviuru zvitatu zvevanhu vanobva kunzvimbo dzakasiyana uye nhanho dzakasiyana dzedzidzo vakapinda, uye 17% yavo vakakwanisa kupa mhinduro chaiyo kumibvunzo iyi. Iye purofesa anonongedza kuti bvunzo pakutanga kuona inoita kunge iri nyore, uye iri nyore kunzwisisa mushure mekujekeswa, asi pamhinduro chaiyo mhinduro inouya mupfungwa kutanga inofanira kusiiwa.

mhinduro dzakajairika

Iyi mibvunzo masendi gumi, maminetsi zana, uye mazuva makumi maviri nemana, zvichiteerana. Asi idzi mhinduro hadzisi idzo. nekuti

mhinduro dzakarurama

Chaizvoizvo masendi mashanu, maminetsi mashanu, uye mazuva makumi mana nemana.

Tsananguro yemhinduro seinotevera

Kana mutengo wechiremwaremwa nebhora pamwe zviri 1.10, uye mutengo weraki wakapfuura mutengo webhora nedhora rimwe chete, uye tinofungidzira kuti mutengo webhora ndi "X", zvino mutengo weiyo bat uye bhora pamwechete "X + (X + 1)."

Ndokunge, x + (x + 1) = 1.10

Izvi zvinoreva kuti 2x + 1 = 1.10

Ndokunge, 2x = 1.10-1

2x = 0.10

x = 0.05

Ndokunge, mutengo webhora "x" wakaenzana nemasendi mashanu.

Kana michina mishanu muchigayo chemachira ichiburitsa zvidimbu zvishanu mumaminitsi mashanu, ipapo muchina wega wega unotora maminetsi mashanu kuburitsa chidimbu chimwe. Uye kana isu taive nemachina zana anoshanda pamwechete, ivo vaizogadzira zvidimbu zana mumaminitsi mashanu futi.

Kana kuwanda kwemaruva kuri kuwedzera zvakapetwa, ndiko kuti, zuva rega rega rakapetwa kaviri zuva rapfuura, uye zuva roga roga rakapfuura ihafu yezuva razvino, zvichireva kuti maruva achafukidza hafu yemahombekombe edziva pazuva re47.
