Which scheme provides the highest discount among the options given?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Two successive discounts of 10% each.
10% + 10%:
→ 1st: 100 → 90
→ 2nd: 90 − 9 = 81
→ Discount = 19%
8% + 11%:
→ 1st: 100 → 92
→ 2nd: 92 − 10.12 = 81.88
→ Discount ≈ 18.12%
8% + 8%:
→ 1st: 100 → 92
→ 2nd: 92 − 7.36 = 84.64
→ Discount ≈ 15.36%
5% + 5%:
→ 1st: 100 → 95
→ 2nd: 95 − 4.75 = 90.25
→ Discount = 9.75%
Highest discount: Two successive discounts of 10% each (19%)
