Saya ada satu soalan...Tapi tak sure dah ada orang tanya atau belum soalan nih.

Ada 8 keping syiling emas...tapi salah satu daripada syiling2 emas ini adalah palsu.Syiling emas yang palsu lebih ringan daripada syiling emas asli,ia boleh dikesan dengan menggunakan dacing penimbang.

Tetapi dacing penimbang yang available cumalah sebuah dacing kuno...ia tak dapat menimbang berat sebenar syiling,ia cuma berdasarkan kaedah timbang-tara.Bermakna syiling emas palsu hanya dapat dikesan dengan menimbangnya bersama syiling emas yang asli...penimbang akan memberat ke arah syiling emas asli kerana ia lebih berat.

Masalahnya...dapatkah kita mengetahui antara 8 syiling emas itu yang mana adalah palsu cuma dengan 2 kali timbangan? Bagaimana caranya?

letak 3 syiling untuk setiap sebelah for a total of 6. kalu sama berat means salah satu dari dua syiling yg tak ditimbang adalah palsu..timbang the two syiling problem solve
kalu 3 syiling from each side from the first step tu tak sama berat..amik sebelah yg ringan...timbang 2 drp 3 syiling tu, one on each side..kalu sama berat means syiling yg tidak ditimbang tu palsu..kalo tak sama berat.means..you got the mothafathar problem solve

harap maklum

solution utk lembu tu is that dia bergerak dalam bulatan, or some other type of loop, tapi ambik bulatan untuk explanation yang senang.
katakan jarak antara kaki kiri dan kaki kanan lembu tu errr....0.8m....aku main teka je, sorry la aku bukannya ada bela lembu.

so beza diantara jarak yang dilalui oleh kaki yang dekat dengan pusat bulatan dan kaki yang jauh dengan pusat bulatan = (2 x pi x R) - (2 x pi x r)
dan R=r+0.8

so beza=(2 x pi x (r+0.8)) - (2 x pi x r)
           =2 x pi x (r+0.8-r)
           =2 x pi x 0.8
           =5m (lebih kurang)

utk beza antara kaki kiri and kanan to be 1km lembu tu kena pusing 200 kali bulatan tu

jejari bulatan (ukur dari pusat ke kaki dekat)=r

200 x 2 x pi x r = 10000m

r= 10000/(400 x pi) = 8m (lebih kurang)

Ni riddle yg paling popular...tak tau la dah ada kat thread ni sebab dah 10 pages..malas nak cari

Three men decided to split the cost of a hotel room. The hotel manager gave them a price of $30.

The men split the bill evenly, each paying $10, and went to their room. However, the hotel manager realized that it was a Wednesday night, which meant the hotel had a special: rooms were only $25. He had overcharged them $5!

He called the bellboy, gave him five one-dollar bills and told him to return it to the men.

When the bellboy explained the situation to the men, they were so pleased at the honesty of the establishment that they promptly tipped the bellboy $2 of the $5 he had returned and each kept $1 for himself.

So each of the three men ended up paying $9 (their original $10, minus $1 back) totaling $27, plus $2 for the bellboy makes $29.

Where did the extra dollar go?

P.S.: jawapan ada dalam internet kalu tak dapat..tapi tak best la..pikir dulu
