Explanation:

- A) Two successive discounts of 10% and 15%:

- First, a 10% discount reduces the price to 90%.

- Then, the 15% discount is applied on the reduced price: 90% * 85% = 76.5%.

- Thus, the effective discount = 100% - 76.5% = 23.5%.

- B) Buy 5 get 2 free:

- Essentially, you get 7 items for the price of 5.

- The effective price per item = 5/7 of the original price.

- This translates to a discount of (7 - 5)/7 = 2/7, or approximately 28.57%.

- Options Analysis:

- Option 1: Incorrect, Option B gives a discount.

- Option 2: Correct, Option B has a discount of 28.57%.

- Option 3: Incorrect, both discounts are not the same.

- Option 4: Incorrect, Option B has a higher discount.

Option 2: B is correct. “”
