Answer 2

Given : The two discounts are,

1. Successive discounts of 40% and 30%
2. A discount of flat 70%

To find : The better discount.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to determine the better discount)

Let, the Marked price of an item = Rs. 100

In case of successive discounts of 40% and 30% :

• Price after 40% discount = 100 - (100 × 40%) = 100 - (100 × 40/100) = 100 - 40 = Rs. 60
• Price after next 30% discount = 60 - (60 × 30%) = 60 - (60 × 30/100) = Rs. 42
• Final discounted price = Rs. 42

In case of discount of flat 70% :

• Price after 70% discount = 100 - (100 × 70%) = 100 - (100 × 70/100) = 100 - 70 =Rs. 30
• Final discounted price = Rs. 30

So,

For successive discounts of 40% and 30%, we can purchase an item with a marked price of Rs. 100, at Rs. 42

For a discount of a flat 70%, we can purchase an item with a marked price of Rs. 100, at Rs. 30

This implies a flat 70% discount is better. (as we will get more discount in this case)

Hence, a discount of a flat 70% is better.
