Successive discounts of 10%, 20% and 30% is equivalent to a single discount of _____?
1. 40.5%
2. 60%
3. 36%
4. 49.6%

Answer 1

Correct Answer - Option 4 : 49.6%

Calculation:

Successive discounts of 10%, 20% and 30% = 100 – [100 × 90% × 80% × 70%]

⇒ 100 – 50.4

⇒ 49.6%

∴ The successive discount of 10%, 20% and 30% is 49.6%
