Dah kichwa kinauma...Let
X=SUNGURA
Y=PAKA
Z=MBWA...
Then formulate equestion
X+y=10,
X+z=20,
Z+y=24
From first equetion,make x sec subject. ..then
X=10-y then substitute into sec equestion
(10-y)+z=20
Z+y=24
Z-y=10
Z+y=24......then solve simultaneous equestion. ..
You will get
Y=7
Z=17
X=3
Then the total weight of mbwa,sungura,na paka. ..
X+y+z=27
