You can put this solution on YOUR website!
Let +c+ = the total cost of the +10+ apples he bought
+c%2F10+ = the original cost / apple
If he steals +3+ and +1+ is rotten, he has +2+ free apples
Now his cost/apple is +c%2F12+
----------------------------
He sells +12+ apples at +c%2F10+ for each apple
+12%2A%28c%2F10%29+=+%286%2F5%29%2Ac+ = his total income from apples
Profit = Income - Cost
Profit = +%286%2F5%29%2Ac+-+c+
Profit = +c%2F5+
--------------
Hope I got it
