Umur Kura-kura

Post by Admin on Thu Sep 11, 2008 11:33 pm

Seekor kera bertanya mengenai umur kura-kura yang dinaikinya. Kura-kura itu berkata "Semasa saya berumur 8 tahun, bapa saya berumur 34 tahun. Sekarang umur bapa saya 3 kali umur saya". Kera itu pun menggarukan kepalanya. Bolehkah anda menolongnya mencari umur kura-kura itu ?

Seekor kera bertanya mengenai umur kura-kura yang dinaikinya.
Kura-kura itu berkata "Semasa saya berumur 8 tahun, bapa saya berumur
34 tahun. Sekarang umur bapa saya 3 kali umur saya". Kera itu pun
menggarukan kepalanya. Bolehkah anda menolongnya mencari umur kura-kura
itu ?

katalah b=bapa
kk=kura-kura

utk "
Semasa saya berumur 8 tahun, bapa saya berumur
34 tahun
"

b-kk=26
b=26+kk----------1

utk "
Sekarang umur bapa saya 3 kali umur saya"
3kk=b
kk=b/3------------2

masuk nilai kk dlm 1:
b=26+(b/3)
b=(78+b)/3
3b=78+b
3b-b=78
2b=78
b=39 tahun

masuk nilai b dlm 1:
b=26+kk
(39)=26+kk
kk=13 tahun

bermakna, umur kura2 (kk) ialah 13 tahun #
