A shopkeeper buys 100 articles at Rs. 50 each and sells them at a 10% profit. Find his total profit.
Correct: B
The cost price of 100 articles is 100 * 50 = Rs. 5000. The selling price of each article is 50 + (50 * 10/100) = 55. The total selling price of 100 articles is 100 * 55 = Rs. 5500. The total profit is given by the formula TP = Total Selling Price - Total Cost Price, where TP is the total profit. Substituting the values, we get TP = 5500 - 5000 = 500.
