First off, and this is besides the point, this question never says that the person actually managed to sell all the fruits. If it were an option, I would have picked "cannot be determined from the data provided". Anyway, we can see that author assumes that the person managed to sell all his fruit at a profit after buying.

Now definition of profit = Selling price - cost price.
Definition of profit% = 100% * (profit)/(cost price).

In this case, the person buys the fruit at a certain cost, and then sells it all. Hence overall profit% refers to the Total money he made as a percentage of the Total money he spent to buy the fruit in the first place.

So , I wrote 150% = (Total profit)/(Total cost).

Is it clear now?

AWESOME!!

gotcha

thank you
