What is the single equivalent discount for three successive discounts of 10%, 20%, and 25%?
Correct Answer: Option A
Explanation:
Let Marked Price = 100. Price after 10% discount = 90. Price after 20% discount = 90 * 0.80 = 72. Price after 25% discount = 72 * 0.75 = 54. Total discount = 100 - 54 = 46. Equivalent discount percentage = 46%.

By selling 90 ball pens for Rs. 160, a person loses 20%. How many ball pens should be sold for Rs. 96 so as to have a profit of 20%?
Correct Answer: Option A
Explanation:
SP of 90 pens = 160. SP of 1 pen = 160/90 = 16/9. Loss = 20%, so CP of 1 pen = (16/9) / 0.8 = 20/9. Desired SP for 20% profit = 1.2 * (20/9) = 24/9 = 8/3. Number of pens for Rs. 96 = 96 / (8/3) = 96 * 3 / 8 = 36.
