Which of the following schemes provide the highest discount?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Two successive discounts of 10% each
Successive discount formula = a + b − (ab / 100)
1 ⇒ 10 + 3 − (10×3/100) = 12.7%
2 ⇒ 10 + 10 − (10×10/100) = 19%
3 ⇒ 7 + 10 − (7×10/100) = 16.3%
4 ⇒ 6 + 10 − (6×10/100) = 15.4%
