Rakesh sold 154 chairs and had a gain equal to the selling price of 66 chairs. What is his profit percentage?

Correct option is B

​Given:
​Number of chairs sold = 154
​Gain = Selling Price of 66 chairs
​Formula Used:
​​$$\text{Profit Percentage} = \left( \frac{\text{Profit}}{\text{Cost Price}} \right) \times 100$$​​​
​Solution:
​Let the Selling Price (SP) of 1 chair be ₹1
​Total SP of 154 chairs = ₹154
​Gain = SP of 54 chairs = ₹66
​So, Cost Price (CP) = SP – Gain = 154 – 66 = ₹88
​Profit Percentage = $$\left( \frac{66}{88} \right) \times 100 = 75\%$$
