 Hello and welcome to the session. In this session, we will discuss the following question. And the question says, the catalog price of a TV set is $300. The shopkeeper gives a discount of 8% on the marked price. He gives a further off-season discount of 5% on the balance. That sales tax at 10% is charged on the remaining amount. Signed, Pat 1, sales tax a customer has to pay for the TV set. Pat 2, the final price he has to pay for the TV. Pat 3, if the customer gives a check at $500, what is the balance amount he gets? Let's start the solution now. We are given that the catalog price of a TV set is $300. So, marked price of the TV is equal to $300. Also, it is given that the shopkeeper gives a discount of 8% on the marked price. So, we will now calculate the discount of 8%. Discount of 8% is equal to 8% of $300. This is equal to $800 into $300. This is equal to $24. So, therefore, price of TV now is equal to the marked price, which is $300 minus discount, which is $24. This is equal to $276. Also, we are given that there is a further off-season discount of 5%. So, off-season discount, 5% is equal to 5% of $276. This is equal to $500 into $276. And this is equal to $13.80. So, now the price of TV is equal to price after the first discount, which is $276 minus the off-season discount, which is $13.80. This is equal to $262.2. Now, in part one, we have to find the sales tax a customer has to pay. We are given that the rate of sales tax is 10%. So, in part one, sales tax of 10% is equal to 10% of the price of the TV after two successive discounts, that is $262.2. This is equal to 10% of $100 into $262.2. This is equal to $26.2. Therefore, sales tax is equal to $26.2. This is the answer for part one. Let's start part two now. In part two, we have to find the final price of the TV. So, the final price of the TV is equal to the discounted price, that is $262.2 plus the sales tax, which is $26.2. This is equal to $288.4. Therefore, final price of the TV is equal to $288.4. This is the answer for part two. Now, we shall solve part three. Part three, we are given that the customer gives a check of $500 and we have to find the balance amount he gets. So, the balance amount the customer gets back is equal to the amount he gives, which is $500 minus the final price of the TV, which is $288.4. This is equal to $211.6. This is the answer for part three. With this, we end our session. Hope you enjoyed the session.
