有個朋友比左500蚊我叫我幫佢去買馬 ........
買馬要用160蚊 ........... 當中是10 , 30 , 30 , 30 , 30 , 30 < 6張馬標
當中佢有一張30的馬標中左49蚊我又幫佢馬上收左 .........
咁我應該比回幾多錢佢 ?

✔ 最佳答案
Gary 講得冇錯, 但係我想糾正, 買馬唔可以用 purchase , 應該係 bet 。

其實好簡單, $500 - $160 = $340 (買完馬嘅餘款)
再加番中咗果$49 咪俾番$389佢.

$389.
1. After purchase, the change should be ($500-$160)=$340
2. You collect $49 in winning.
3. $340+$49=$389.

Then your friend does not know how HKJC works.
The winning includes the initial cost ($30). Your another friend assume you can get it as well (so you will get $30+$49=$79).
This is how $359 comes up (and it is wrong).
The actual profit from the winning is $19.
