 Hello and welcome to the session. In this session we will discuss the following question and the question says a man bought a TV set for $300 and he sold it at a profit of 15% signed the selling price. Let's start the solution now. First we will do an assumption. Let the cost price is equal to $100. Now we are given that the profit is 15%. So let's calculate the profit on this cost price which is $100. We get profit is equal to 15% of the cost price which we have assumed to be $100. This is equal to 15 upon 100 into $100. Zeros get cancelled and this is equal to $15. So therefore selling price at a profit of 15% is equal to the cost price which is $100 plus the profit which is $15 and this is equal to $115. So we get then cost price is $100. Selling price is equal to $115. Now in the question we are given the cost price which is $300 and we have to find the selling price. So therefore when cost price is $300, selling price is equal to $115 upon 100 into $300. The zeros get cancelled. This is equal to $345. So the final answer is selling price is equal to $345. With this we end our session. Hope you enjoyed the session.
