Q1.A shopkeeper marked an item 25% above its cost price. During a sale, he offered a discount of 10%. What was his profit percentage?
Correct Answer: B
Let CP=100. Marked Price (MP) = 125. Selling Price (SP) = 125 - (10% of 125) = 125 - 12.5 = 112.5. Profit = 12.5%.
Q2.Profit % question (10% less buy, 10% more sell)?
Correct Answer: C
Standard combined formula: New ratio is 110/90. Profit = (110 - 90)/90 = 20/90 = 22.22%.
Q3.There is 10%, 20% and 40% discount on a thing. What single discount is equivalent to all of them together?
Correct Answer: B
Multiplier = (1-0.10)*(1-0.20)*(1-0.40) = 0.9 * 0.8 * 0.6 = 0.432. Net discount = 1 - 0.432 = 0.568 = 56.8%.
Q4.If a product is Rs. 500 net of a 3% discount, what is its gross price?
Correct Answer: A
Gross Price = Net Price / (1 - Discount Rate) = 500 / (1 - 0.03) = 500 / 0.97 ≈ Rs. 515.46.
