Je unaweza kutumia akili yako vizur?

Hebu jaribu hii, babu na mjukuu wake walikuwa ni wafugaji wa njiwa. Siku moja walitaniana Mjukuu; babu nipe njiwa mmoja ili tuwe na njiwa idadi sawa,
Babu; mimi ni babu yako nipe njiwa wako mmoja ili nikuzidi mara 2,

haya hebu nambie sasa babu alikuwa na njiwa wangapi na mjukuu alikuwa na njiwa wangapi?

Mfano
Babu=b,Mjukuu=m

1.Babu akimpa mjukuu njiwa,itakuwa....m+1
Lakini babu atakuwa amepungukiwa njiwa mmoja..b-1
Vilevile mjukuu anasema kwamba watakuwa sawa baada ya babu kumpa njiwa,hivyo kihesabu;
m+1=b-1....(i)

2.Mjukuu akimpa babu njiwa itakuwa ...b+1
Lakini mjukuu atakuwa amepungukiwa njiwa mmoja...m-1
Vilevile babu anasema kwamba akakuwa amemzidi mjukuu mara mbili baada ya kupewa njiwa,hivyo kimahesabu;
b+1=2(m+1)....(ii)
Ukifanya mbadala mlinganyo namba moja kwenye mlinganyo namba mbili (substitution)
(m+2)+1=2(m-1)
m+2+1=2m-2
m+3=2m-2
m-2m=-2-3
-m=-5
m=5

lakini,b+1=2m-2
b=2(5)-3
b=7

Hivyo babu ana njiwa 7,mjukuu ana njiwa 5
