Hi Vasudha, Here it is the case bcoz the question is asking for it. Taking ratio is helpful when either asked in the question or when we need to find CP if asked but here we have been asked to find the difference between the percentages so the given solution is correct. There is no other way to get the difference between their percentages gain/loss. I hope this helps you, please close the ticket if your query has been resolved.
