If the cost price of an article is Rs. 180 and the selling price is Rs. 216, what is the profit percentage? MCQ with Answer and Explanation

Explanation:
CP1 = 2400/1.2 = 2000. CP2 = 2400/0.8 = 3000. Total CP = 5000. Total SP = 4800. Loss = 5000 - 4800 = Rs. 200.

Explanation:
Let CP of 1 meter = 1. CP of 20 meters = 20. Profit = CP of 4 meters = 4. Profit % = (4/20) * 100 = 20%.

Explanation:
Let initial Cost Price = 100x. Initial Selling Price = 112x. New Cost Price = 90x. New Selling Price = 90x * 1.30 = 117x. Difference in Selling Price = 117x - 112x = 5x. 5x = 5.75. x = 1.15. Cost Price = 100 * 1.15 = 115.
