jok3333 [9.3K]

Answer: The percent gain was 25%.

Step-by-step explanation:

Given, Cost price of lot = $1,200

Selling price of lot = $1,500

The percent gain = \dfrac{\text{selling price- cost price}}{\text{cost price}}\times100

⇒ Percent gain =\dfrac{1500-1200}{1200}\times100\%

\Rightarrow\text{ Percent gain}=\dfrac{300}{1200}\times100\%\\\\\Rightarrow\text{ Percent gain}=\dfrac{1}{4}\times100\%\\\\\Rightarrow\text{ Percent gain}=25\%

Hence, the percent gain was 25% based on his purchase.
