Gain percentage = ?
The gain percentage is the same as the percentage profit on a trade.
The formula is given as:
Gain percentage = ![\frac{Profit}{Cost price} x 100](https://tex.z-dn.net/?f=%5Cfrac%7BProfit%7D%7BCost%20price%7D%20%20x%20100)
Profit = Selling price - Cost price
= Nu.29.30 - Nu.28.30
= Nu. 1
Now input the parameters and solve;
Gain percentage = ![\frac{1}{28.3} x 100](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B28.3%7D%20x%20100)
= 3.5%
The gain percent is 3.5%
