Marked Price: The original price of the item before any discounts or taxes are applied.
Discount: The reduction in price given by the shopkeeper.
Sales Tax: The additional amount charged on the discounted price.

Let's solve the problem step by step:

Step 1: Calculate the discounted price
The shopkeeper allows a discount of 10% on the marked price. This means the customer only pays 90% of the marked price.
Discounted Price = Marked Price - (Discount % * Marked Price)
Discounted Price = Marked Price - (10/100 * Marked Price)
Discounted Price = Marked Price - 0.1 * Marked Price
Discounted Price = Marked Price - 0.1 * Marked Price
Discounted Price = Marked Price * (1 - 0.1)
Discounted Price = Marked Price * 0.9

Step 2: Calculate the price including sales tax
The shopkeeper charges a sales tax of 8% on the discounted price. This means the customer pays 108% of the discounted price.
Price Including Sales Tax = Discounted Price + (Sales Tax % * Discounted Price)
Price Including Sales Tax = Discounted Price + (8/100 * Discounted Price)
Price Including Sales Tax = Discounted Price + 0.08 * Discounted Price
Price Including Sales Tax = Discounted Price * (1 + 0.08)
Price Including Sales Tax = Marked Price * 0.9 * (1 + 0.08)
Price Including Sales Tax = Marked Price * 0.972

Step 3: Determine the marked price
According to the problem, the customer pays Rs 680.40 as the price including the sales tax.
Price Including Sales Tax = Marked Price * 0.972
Rs 680.40 = Marked Price * 0.972
Marked Price = Rs 680.40 / 0.972
Marked Price ≈ Rs 700

Therefore, the marked price of the item is Rs 700, which is option B.
