A shopkeeper gives three consecutive discounts 10%, 20% and 25% after which he sells the article at a profit of 8% on the cost price. Had he sold the article after the first discount, how much profit would he have got?

Explanation

Let MP = 100. SP after discounts = 100 \times 0.9 \times 0.8 \times 0.75 = 54. Since profit is 8%, CP = \frac{54}{1.08} = 50. After only the first 10% discount, SP = 90. Profit = 90 - 50 = 40. Profit % = \frac{40}{50} \times 100 = 80\%. 80% is not in the options.
