This one I guess many of you will get it right.
Tap A fills a container in 3 hours. Tap B fills the same container in 2 hours. Tap C empties the same container in 6 hours. When all the taps are turned on at the same time, how long does it take to fill the container?

SOLUTION
If are opened simultaneously
Time for water flowing into a container
Ta + Tb
3/2+ 2/2= 5/2 hours
Time for empty a container
Is done by tap C
Tc = 6 hours

The difference in time is a time taken to filk container
6 - 5/2= 7/2 hour = 3.5 hours
This is a time for filling a container if all tap are opened simultaneously

Answer = 3.5 hours

Mpiga era, swali lingekuwa rahisi hivyo nisingelitoa, jaribu tena, bado

Mkuu hapa hakuna ujanja ujanja nakuwekea kifaransa ,Haya kifaransa hicho


Un vendeur de fruits avait des oranges, les poires et les mangues. Après avoir vendu certains d'entre eux, il y avait 6 poires pour tous les 5 oranges àgauche et à 7 oranges pour tous les 3 mangues gauche. Il a vendu 168 oranges. Le nombre de poires vendus était le même que le nombre de mangues vendues. Il avait un total de 456 poires et mangues à gauche.
Combien d'oranges avait - il tout d' abord?



mkuu lugha yako hiyoooooooo.tunasubiri jibu na uwe umepataa

Jibu ameishatoa Idoyo, labda kama unataka jinsi ya kulikokotoa

JIBU NI Machungwa 448

Njia ni kama ifuatavyo

Let machungwa yaliyobaki ni x

Let maembe yaliyobaki ni y

Let peas yaliyobaki ni z

Peas machungwa

6 ----------------------------------> 5

X(cross multiplication)

Z ----------------------------------->x


6X=5Z

Z=6/5*X


Sasa tuhamie kwa machungwa na maembe

machungwa maembe

7 ------------------------------------------> 3

X(cross multiplication)


x ------------------------------------ ------>y

y=3/7*X

x=7/3*y

But total of remains peas and maembe ni 456

Z+y=456………(i)

Z=6/5(7/3*y)

Z=14/5*y

5z=14y

5z-14y=0………….(ii)

Solving equations …(i) and ……(ii) simultaneous

5z-14y=0

Z+y=456

Z=336,y=120

Recall x=7/3*y

x=7/3*120

x=280(haya ni machungwa yaliyobaki )

machungwa yote yaliyokuwepo= machungwa yaliyobaki + machungwa yaliyouzwa

machungwa yote yaliyokuwepo=280+168

machungwa yote yaliyokuwepo =448


Hilo ndio jibu wakuu,kwa kuwa alitaka kujua kuhusu machungwa basi naishia hapo.

hahahaha Idoyo, nitaendelea hapahapa naona wewe kichwa. ngoja mchana nitatoa jingine. Hongera

Muuza matunda alikuwa na machungwa, peas na maembe. Baada ya kuuza baadhi, zilibaki peas 6 kwa kila machungwa 5 yaliyobaki na machungwa 7 kwa kila maembe 3 yaliyobaki. Aliuza machungwa 168. Idadi ya peas na maembe aliyouza zililingana. Jumla ya peas na maembe yaliyobaki ni 456.
Je alikuwa na machungwa mangapi mwanzoni?
