A student was getting the following four offers on the purchase of a book:
I - Two successive discounts of 20% and 20%
II - Two successive discounts of 25% and 15%
III - Two successive discounts of 30% and 10%
IV - Two successive discounts of 5% and 35%
Formula used:
Effective Discount (ED) = d1 + d2 - (d1 × d2) / 100
Where, d1 and d2 are the successive discount percentages.
Calculations:
For I:
⇒ ED = 20 + 20 - (20 × 20) / 100
⇒ ED = 40 - 4 = 36%
For II:
⇒ ED = 25 + 15 - (25 × 15) / 100
⇒ ED = 40 - 3.75 = 36.25%
For III:
⇒ ED = 30 + 10 - (30 × 10) / 100
⇒ ED = 40 - 3 = 37%
For IV:
⇒ ED = 5 + 35 - (5 × 35) / 100
⇒ ED = 40 - 1.75 = 38.25%
∴ The correct answer is option (4).
