# SOLVING FROM OPTION

Question: A trader calculates his profit on the selling price and says it to be 20%. Find the actual profit.

1. 18%
2. 20%
3. 25%
4. 30%

Answer: Since profit has been calculated on selling price instead of on cost price, so correct percentage profit will be more than the calculated profit. This means that options ‘a’ and ‘b can be easily ruled out. This leaves us with options ‘c’ and ‘d’.

Let us, proceed by using the option ‘c’, i.e. 25%.
If Cost Price = Rs. 100
Then profit = Rs. 25
Then, Selling Price = Rs. 125
Now, 25 is 20% of Rs. 125; which is matching with the figure in question.
Hence, option ‘c’ is the right answer.
