D. 85.5

Answer

To solve the problem step by step, we will calculate the total discount applied to the ball and then determine the final amount the customer has to pay.

### Step 1: Calculate the first discount
The original price of the ball is Rs 100. The store offers a 10% discount on this price.

**Calculation:**
- First Discount = 10% of 100
- First Discount = (10/100) * 100 = Rs 10

### Step 2: Calculate the price after the first discount
Now, we subtract the first discount from the original price to find the new price.

**Calculation:**
- Price after first discount = Original Price - First Discount
- Price after first discount = 100 - 10 = Rs 90

### Step 3: Calculate the second discount
The store offers a further 5% discount on the reduced price (which is now Rs 90).

**Calculation:**
- Second Discount = 5% of 90
- Second Discount = (5/100) * 90 = Rs 4.5

### Step 4: Calculate the final price after both discounts
Now, we subtract the second discount from the price after the first discount to find the final amount to be paid.

**Calculation:**
- Final Price = Price after first discount - Second Discount
- Final Price = 90 - 4.5 = Rs 85.5

### Final Answer
The amount to be paid by the customer is Rs 85.5.
