A shopkeeper bought an article for Rs. 500. At what price (in Rs. ) should he sell the article to make 26% profit?

Correct option is B

​Given:
​Cost Price (CP) = Rs. 500
Required Profit = 26%
​Formula Used:
​​$$\text{Selling Price (SP)} = \text{Cost Price (CP)} \times \left(1 + \frac{\text{Profit\%}}{100} \right)$$​​​
​Solution:
​​$$\text{SP} = 500 \times \left(1 + \frac{26}{100} \right) \\= 500 \times \left( \frac{126}{100} \right) \\= \frac{500\times 126}{100} \\= 630$$​​​​
