Three shopkeepers A, B and C marked an identical article at ₹4820. A, B and C sold their article on successive discounts of 20% and 20%; 25% and 15%; 30% and 10% respectively. Which shopkeeper gives the maximum discount and how much (in Rs)?
Answer & explanation
Correct answer: option 2
Marked price of article = Rs.4820
Total discount when a% and b% are successive discounts = (a + b) - \(\frac{ab}{100}\)
Total discount for A = (20 + 20) - \(\frac{400}{100}\) = 36%
Discount for A = 4820 × \(\frac{36}{100}\) = Rs.1735.2
Total discount for B = (15 + 25) - \(\frac{375}{100}\) = 36.25%
Discount for B = 4820 × \(\frac{36.25}{100}\) = Rs.1747.25
Total discount for C = (30 + 10) - \(\frac{300}{100}\) = 37%
Discount for C = 4820 × \(\frac{37}{100}\) = Rs.1783.4
