Answer:
20%
Step-by-step explanation:
Given that,
Initial price = 1500
Final price = 1800
We need to find the percentage of the profit or loss. As SP is more than Cp, he will have profit. The profit percentage is given by :
[tex]\%=\dfrac{1800-1500}{1500}\times 100\\\\=20\%[/tex]
So, the required percentage is 20%.
