Let P be mchele
P - 1/4P = 3/4P
1/3 x 3/4P = 3/12P
3/4P - 3/12P = 60
6/12P = 60
P = 60x2
P = 120
Alikuwa na kilo 120

We kweli madenge.Anyway ushawahi kufanya swali ukicheki raia majibu yanaendana ila wewe ndo kwanza jibu lako hata robo halifanani hadi unaanza kuhakikisha kama swali ulofanya ndo lenyewe

Nataka chato

No.. you could be right Ila approach uliyotumia kwenye case 'ya kilichobaki'

1/3 of 60
Hahahah

Nimetumia njia rahisi inayoeleweka sanaa...mchele ulikuwa 120 kilos

Akala robo ya mchele(1/4) ambayo inakuwa robo times kilos zote ambayo inakuwa 30
Akauza theluthi(1/3) ya kilichobaki(kupata kilichobaki unachukua kilos zote (120) unatoa alizokula (30) unapata 90(kilochobaki) times 1/3 unapata 30
Kwenye swali anasema kilichobaki ni 60 kilos so inabalance kabisa

Alichokula(30)+Alichouza(30)+Kilichobaki(60)=120 kilos

Njia.
Fikiria Y iwe ni jumla ya Kg za mchele alizo kuwa nazo Alpha

Mchele alio kula=1/4 ya Y=1/4xY=1/4Y

Mchele alio uza=1/3 ya mchele uliobaki
Lakini Mchele uliobaki baada ya kula=Jumla ya mchele-Mchele alio kula =Y-1/4Y=3/4Y
Kwa hiyo,
Mchele alio uza=1/3 ya 3/4Y =1/3x3/4Y
Mchele aliouza= (1x3)/(3x4)Y=3/12Y=1/4Y

Jumla ya mchele wote=Mchele alio kula+Mchele alio uza + Mchele alio baki nao
Y=1/4Y+1/4Y+60
Zidisha na 4 kila upande
4Y=Y+Y+240
4Y=2Y+240
4Y-2Y=240
2Y=240
Y=120

Kwa hiyo Alpha alikua na Kg 120 za mchele
