i am still confused.. this is how i approached:
A person sells to items at the sime price let's say at 100$.
First one is sold at 25% loss: x*0,75=100 --> x = 133,333 Total loss = 100/3 $
Second one is sold at 25% profit: x*1,25 = 100 --> x = 80 Total profit = 20 $
I interpreted profit/loss percentage as 20/(100/3) = 0,6 That's where I'd stop.. Can you correct this please?
