 Hello and welcome to the session. In this session, first we will discuss about the scouts. Before starting with that, let's see what is the definition of marked price. The price, printed on an article, say on a tag or the listed price. You can also say the advertised remarked price, as if abbreviated as MP, now let's see what is discount, the amount deducted or the marked price, or you can say retained discounts for retainers, reduce the price of the article to increase the sale or to the sales of the old damaged or perishable goods and this deducted amount from the marked price is the discount. We have the definition to deduct them, you can also say article. The discount is always calculated on the marked price. Now we will discuss some formulae, like the selling price SP is equal to the marked price MP minus is equal to the marked price minus the selling price MP minus discount and in place of discount we can write this that is D which is the discount percent multiplied by marked price whole upon 100. We have the selling price SP is equal to 100 minus discount percent D this whole upon 100 and this whole multiplied by the marked price MP. An example in which we are given the marked price of an article has 50 dollars 15 percent denoted by D percent. So we are given the marked price of the article and the discount percent is formula that is discount is equal to the discount percent into marked price upon 100. We can find out the discount, so discount is equal to D into the marked price MP upon 100. Fitting the respective values we get 15 into 50 and this whole upon 100. So this is equal to 7.50 dollars. We can also find out the selling price by subtracting the discount from the marked price article is equal to the marked price minus the discount that is now the marked price is and the discount is 7.50 dollars. So 7.50 dollars subtracted from 50 dollars gives us 32.50 dollars. So this is the selling price of the article. We can also find out the selling price of the article using this formula that is 100 minus discount percent upon 100 this whole multiplied by the marked price. That is selling price SP is equal to 100 minus D upon 100 and this whole multiplied by MP. So we have selling price SP is equal to 100 minus now the discount percent is so 100 minus 15 this whole upon 100 and this whole multiplied by 50 which is the marked price. Further we have 100 minus 15 that 85 upon 2 dollars is the selling price. This is equal to next we discuss about the successive discounts. The other successive discounts is after the first discount is found by subtracting the first discount from the marked price. We subtract the second discount the marked price after the second discount and this process continues like this. D2 percent MP then the selling price is equal to 1 minus D1 upon 100 this whole multiplied by 1 minus D2 upon 100 and this whole multiplied by the marked price MP. There is no principle and example we are given the marked price 150 dollars and 20 percent. So using this formula we will find out the selling price of the article given the marked price and 2 successive discount. The selling price of the article is equal to 1 minus D1 which is 30 upon 100 this whole into 1 minus D2 which is 20 upon 100 and this whole into the marked price which is 150. This is equal to if into where the 0 cancels with the 0, the 0 cancels with the 0, the 0 cancels with the 0 and 5, 3 times is 15, 5, 2 times is 12. The selling price is shown for pure under-accessive discounts.
