Three back-to-back discounts of 10%, 20% and 25% work out to a single discount of: / एक के बाद एक दी गई 10%, 20% और 25% की तीन छूटें मिलकर एकल छूट बनती हैं:
1.
46% / 46%
2.
55% / 55%
3.
45% / 45%
4.
48.5% / 48.5%
Correct Answer: 46% / 46%
Net price fraction = 0.90 × 0.80 × 0.75 = 0.54, so the equivalent single discount is 1 - 0.54 = 46%. Adding the discounts (55%) is the trap. / शुद्ध मूल्य अंश = 0.90 × 0.80 × 0.75 = 0.54, अतः समतुल्य एकल छूट = 1 - 0.54 = 46%। छूटों को जोड़ना (55%) भ्रम है।
