Answer:
Pretty sure a loss of -27.08%, check the formula for loss percent
Explanation:
Assuming this means 120 for 20 oranges.
so for 200, every 20 was bought for 120.
There are 10 20s in 200 so that's 10 score, which means 120*10 = 1200
So 1200 was spent.
25 were rotten which means they now have 175
selling for 5 each means 5*175 = 875 was the profit.
Since they spent 1200 and made 875 there was a loss.
Then I think percent loss/ gain is (revenue - cost)/cost where revenue is what was made and cost is what was spent. so this makes (875-1200)/1200 = -.2708 = -27.08%
Kinda rusty on this so double check what loss percent is.
