Question:
Find the single discount rate percentage equivalent to the successive discounts of 10%, 20% and 20%.
10%, 20% और 20% की लगातार छूट के समतुल्य एकल छूट दर प्रतिशत ज्ञात कीजिए।
Options:
- a) 40%
- b) 42.4%
- c) 50%
- d) 54.6%
- a) 40%
- b) 42.4%
- c) 50%
- d) 54.6%
correct answer : b)
Explanation:
Successive discount = 100 – (100 * 0.9 * 0.8 * 0.8) = 100 – 57.6 = 42.4%.
क्रमिक छूट = 100 – (100 * 0.9 * 0.8 * 0.8) = 100 – 57.6 = 42.4%।
