Dog = 17kg
Cat= 7kg
Rat=3kg
Kwa hiyo dog, cat, plus rat = 17 + 7 + 3 = 27kg hili ndiyo jibu lake barikiwa lete fumbo jingine kwa mhenga wa hesabu.

Mkuu umeflow vizuri ila hitimisho ni 27kg.

C=17, b=7, a=3

Sum= 27kg

Aisee, hapo kwenye b ndo nimezingua. (Ngoja nifanye edit).

Kimahesabu hapo ninapata marks ngapi?

Boss kweli mouse ana kg 3?

Kulingana na swali ndio.
Paka 7 + Panya 3 = 10
Paka 7 + Mbwa 17 = 24
Mbwa 17 + Panya 3 = 20
Mbwa + Paka + Panya (17 + 7 + 3 = 27)

Mbona na wewe umebadilisha ulikuwa umeandika 28?

Haha mkuu mwanzon nlipigia mahesabu kichwan.
Scenario kichwan ilikuwa hivi.
Kama mbwa + paka =24
then mbwa=24-paka

Sasa nikaja ule mchoro wa mbwa na panya
mbwa + panya = 20:
So nikasubstitute badala ya mbwa nikaweka 24-paka

So ikaja hivi
24-paka+panya = 20
Nikazipanga ikawa
paka-panya = 24-20= 4

Sasa hapa ndo kichwa kilipofail
Nikawa ninajua sasa akilini kuwa
a)Paka-panya=4
b)paka+panya=10

Sasa ubongo ukakimbilia kufikiria hapo paka ni 6 na panya ni 4 (itakuwa kwasababu ya uwepo wa hiyo 4 kwenye (a)ndo ilinichanganya) wala sikuwaza kuhusu 7 na 3 na ndo hapo nilipofail..
wakati 6-4 haileti 4

Basi the way ulivyopiga mahesabu kichwani basi hata mimi ilikuwa hivyo hivyo, nilipoona haiko sawa ndio nikapiga tena na kupata jibu 27....ile 28 niliandika bila kukusudia.

Wote mmekosa..subirini jibu langu

Utatoa autoii?!

Kwahiyo umejisahishia mwenyewe na umejiwekea vemaa?

Soln:
Let a = mouse, b = cat and c = dog.

a + b = 10 ---(i)

a + c = 20 ---(ii)

b + c = 24 ---(iii)

From eqn (i) make a the subject.

a = 10 - b ---(iv)

Substitute eqn (iv) into equation (ii).

10 - b + c = 20.

Make b the subject:

b = c - 10 ---(v).

Then, substitute eqn (v) into eqn (iii):

c - 10 + c = 24.

2c = 34,

c = 17.

Eqn (v): b = c - 10, b = 17 - 10 = 7.

Eqn (iv): a = 10 - b, a = 10 - 7 = 3.

Therefore: a + b + c = 17 + 7 + 3 = 27.

The answer is 30.
