Answer:
-20%
Step-by-step explanation:
We have to Harry bought a quantity of fruit.
He sold half, that is 50% but I earn 60%, that is to say that here he made 10% of profits.
Then he sold 1/4 of the total, that is 25% but he took 20% of profits, that is to say that in this case he obtained 5% of losses.
They tell us that the rest was spoiled, that is, 100 - 50 - 25 = 25% was spoiled, and all that is lost, in the end the balance is as follows:
10% - 5% - 25% = -20%
That is to say that in general it lost 20% of the total.
