too easy, man! That 100 buck he got is fake and he has to pay one more 100 buck to the other store. Therefore, he lost 200 bucks in total.

作者: manstein 時間: 2007-10-12 05:25 PM

correct answer is 100 bucks...tvb now,tvbnow,bttvb; i9 ?4 i: L' M7 N u; P
the shop owner take $100 fake money to exchange $100 real money5.39.217.769 N }" h, e0 U6 W" B" ^& D
den out of tis $100 real money, he return $75 to the man who buy the product.
so the shop owner left $25 real money in his hand (tis money belongs to the hawker)
so when the hawker comes back wif the fake money n ask for compensation) k% r) y3 @& m% m, j; w: L8 W
the shop owner gotta take out another $75 out fr his own pocket n return the hawker (together wif the $25 on his hand, it makes up to $100)
hence, the shop owner total lost $75 (fr his own pocket) + $25 (for the product he sold) . Q# g3 ~$ u8 u0 v1 g
no wonder they said got 85% of ppl all got it wrong...

$200.00

作者: puiming 時間: 2007-10-13 10:34 AM

its should be 225 because in the whole process if the money is real in the first place ,the shop owner would have make 25 on the sale , and because the money`s fake he lost 100 back to the stall keeper + 75 change +25 actual prodult +25 sales =225

作者: puiming 時間: 2007-10-13 10:43 AM

sorry all wrong, its 100 + 25 sales =125

作者: zxy39apple 時間: 2007-10-13 01:12 PM

作者: ching_laisc 時間: 2007-10-14 08:09 PM

樓主的答案.......5.39.217.76: [" S- K, u/ U0 {# V, x& _
應是$175 + 店主的東西(標價$25)

註:店主的東西(標價$25) 可能其價值>$25 / <$25 不能用標價當作真的損失
