You have an initial capital of RM45,000 and you are thinking of setting up an online store to sell certain goods. You have a choice of 20 different types of goods. The following table shows you the costs and profits of the goods:

For each type of goods, your supplier will only supply you a maximum of 5 items.

What is the highest profit that you can generate? Please also show the combination of goods that allow you to generate this profit.

The above data can be downloaded in csv format here.

If you have a combination of goods that meets all the conditions above, and you are our newsletter subscriber at 12 noon on 6 August 2013 (Competition Date), you stand a chance to win a cash prize of RM100.  Please note that the Cutoff Time for this competition is 11 August 2013 18:00 (KL time)

Competition for the RM100 cash prize is now closed.  We have 13 valid entries (12 found optimal solution).

The above brain teaser was only open to our newsletter subscribers as at 6 August 2013.

If you submitted an answer and your name does not appear on the Honour Roll, it is likely that you were not a newsletter subscriber at the competition date.

Based on the closing FBMKLCI as at 12 August 2013 of 1,784.57, we take 57 and divide by 58.  The remainder is 57, add 1 to 57 we get 58.

So the winner is "Karen".  Congratulations!

6. The winner will walk away with RM100 cash.
7. Please make sure your name as entered in the submission form matches the name you use in your bank account as the prize money will be transferred directly to your bank account and we are unable to pay you if the names do not match.
8. You may submit more than 1 time if you find a new combination that gives you a higher profit. However, only 1 entry per day is allowed.  If you submit more than 1 entry per day, only the first entry for that day will be considered. Day is based on KL time zone.
9. Only 1 email address per person is allowed. We reserve the right to disqualify you if we discover that you submit more than 1 entry using different email addresses.
10. If no valid entry is received by the Cutoff Time, the first valid entry submitted after the Cutoff Time wins the cash reward.
11. A valid answer is a combination that costs you not more than your initial capital (RM45,000) and for each type of goods in that combination you have 5 or less items chosen. The number of items for each type of goods should also be a whole number.
12. Winner will be announced on this page using the nickname.
13. If case of dispute, our decision is final and binding.

The winner will be determined based on the closing FBMKLCI on the 1st trading day immediately after the Cutoff Time as follows:

1. Take only the 2 digits after the decimal point, and lets say this 2-digit number is X.
2. Divide X by N, where N is the total lucky numbers allocated at the Cutoff Time. Take the remainder and add 1.
3. From the number obtained in Step 2, match it with the lucky numbers as shown in the Honour Roll to decide the winner.

As an illustration, assuming 11 valid entries and assuming that the closing FBMKLCI is 1,623.31:

1. X is 31 based on the 2-digit number after the decimal point of closing FBMKLCI.
2. Since there are 11 valid entries, in total 56 lucky numbers are allocated (01 to 56).
3. Divide 31 by 56 gives a remainder of 31.  Add 1 and we get 32.
4. The 4th person on the Honour List has lucky number 32 and hence is the winner.
5. Please note that by intention, this method may favour slightly those who submit their entries early.
