Sometimes a radio program is added to the carrier in such a way that the program signal causes fluctuations in the carrier's frequency. This is called frequency modulation (FM). Another way of sending a radio signal is to make the peaks of the carrier wave bigger or smaller.
Calculating the percentage profit made. It is also possible to work out the percentage profit that is made on a deal. This is done using the profit and the price that something cost originally, before it was sold on (the Cost Price). Percentage Profit = (profit/cost price) x 100%. The next example shows how this is done. Example.
1 You may want to convert stock profits to a percentage. 2  Doing this makes it easy to compare how well investments of different size and type have performed. 3  To convert to percentage gain, divide the profit by the cost basis and multiply by 100. 4  For example, suppose your cost basis was $5,000 and your profit $700.ubtract the cost basis from the total proceeds to calculate your stock profit. Note that if the cost basis is greater than the total proceeds from selling the stock, your answer will be a negative number.
