The marked price of a laptop is ₹ 24,000. If after allowing two successive discounts of x% and 10% on the marked price, it is sold for ₹ 18,360. Find the value of x?

• A. 12
• B. 20
• C. 10
• D. 15

Answer 1

Answer:

D. 15

18,360 = 24,000 × (100 –x)/100 × 90/100 ⇒ 18,360 = 24 × (100 – x) × 9 ⇒ 2,040 = 24 × (100 – x) ⇒ 85 = (100 – x) ⇒ x = (100 – 85) ⇒ x = 15
