Successive discounts of 20% and 15% are equal to a single equivalent discount of what percentage? MCQ with Answer and Explanation

Explanation:
The difference between an 8% gain and a 4% loss is 12% of the cost price. So, 12% of CP = 120. CP = (120 * 100) / 12 = Rs. 1000.

Explanation:
Selling Price of 12 items = 60. Selling Price of 1 item = 5. Cost Price of 1 item = 5 / 0.75 = 20 / 3. Desired Selling Price for 25% profit = (20 / 3) * 1.25 = 25 / 3. Number of items for Rs. 100 = 100 / (25 / 3) = 12 items.

Explanation:
Cost Price = (1920 + 1280) / 2 = 3200 / 2 = 1600. Desired Selling Price for 25% profit = 1600 * 1.25 = 2000.
