Final answer:
To find the amount of discount and sale price of the TV after a 20% discount, multiply the MRP by 20% to get the amount of discount, then subtract the amount of discount from the MRP to get the sale price.
Step-by-step explanation:
To find the amount of discount on the TV, you need to calculate 20% of the MRP. To do this, you multiply the MRP by 20% (0.2). So, the amount of discount is 13300 * 0.2 = 2660.
Now, to find the sale price, you subtract the amount of discount from the MRP. So, the sale price is 13300 - 2660 = 10640.
Therefore, the amount of discount on the TV is 2660 and the sale price is 10640.
