A company offers three types of successive discounts: First offer: 25% and 5%, Second offer: 20% and 10%, Third offer: 15% and 15%. Which offer is the best for a customer?

Correct option is C

Given:

Three successive discount offers:

First offer: 25% and 5%

Second offer: 20% and 10%

Third offer: 15% and 15%

Formula Used:
Successive discounts formula:

Net Discount % = a + b - $$\frac{ab}{100}$$​​

Where a% and b% are the successive discounts.

Solution:

First Offer (25% and 5%) :

​$$= 25 + 5 - \frac{25 \times 5}{100} = 30 - 1.25 = 28.75\%$$​​

Second Offer (20% and 10%):

​$$= 20 + 10 - \frac{20 \times 10}{100} = 30 - 2 = 28\%$$​​

Third Offer (15% and 15%):

​$$= 15 + 15 - \frac{15 \times 15}{100} = 30 - 2.25 = 27.75\%$$​​

Thus, First Offer (25% and 5%) is the best for the customer.
