Which of the following transactions is the best when considering the corresponding profit percentage?

Formula Used: ​

​$$\text { Profit percentage} = \frac{\text{Profit}}{\text{Cost Price}}\times 100$$ 

From option(a) 
​Cost price Rs.50, profit Rs. 24 

Profit percentage = $$\frac{24}{50}\times100 = 48\%$$ 

From option(b)

​Cost price Rs.40, profit Rs. 15 

Profit % = $$\frac{15}{40}\times100 = 37.5\%$$ 

From option(c) 

​Cost price Rs.60, profit Rs. 24 

Profit% = $$\frac{24}{60}\times100 = 40\%$$ 

From option(d) 

​Cost price Rs.36, profit Rs. 18 

Profit% = $$\frac{18}{36}\times100 = 50\%$$ 

After observing all the above options, we can see that option (d) gives the maximum profit of 50 % .
