 Hello and welcome to the session. In this session we will discuss the following question and the question says, after successive discounts of 20% and 5% have been granted, the net price of the laptop is $380. What was the list price? Let's start the solution now. We will do an assumption first. Suppose the list price of the laptop is equal to $100. Now it is given that the first discount is of 20%. First discount at 20% is equal to 20 upon 100 into $100. Zeros get cancelled and this is equal to $20. So the net amount after first discount is equal to the list price that is $100 minus the first discount that is $20. This is equal to $80. Also it is given that the second discount is of 5%. So second discount 5% is equal to 5 upon 100 into the net amount after first discount which is $80. Zero gets cancelled, 5 2 times is 10 and 2 4 times is 8. So this is equal to $4. So the net amount after second discount is equal to the net amount after first discount which is $80 minus $80. The second discount which is $4 and this is equal to $76. Now we had assumed the list price to be $100 and we got the net price of $76. So we can say that if the net price is $76 then list price is equal to $100. In the question we are given that net price of the laptop is $380 and we have to find the list price. So therefore if the net price is $380 list price is equal to $100 upon 76 into $380. Now 19 4 times is 76 and 20 times is 380. Also 4 5 times is 20. So this is equal to $500. So the final answer is list price is equal to $500. With this we end our session. Hope you enjoyed the session.
