Find cost price from given selling price and profit or loss percentage in C++
Consider we have the selling price, and percentage of profit or loss is given. We have to find the cost price of the product. The formula is like below −
$$Cost \: Price = \frac{Sell Price * 100}{100 + Percentage \: Profit}$$
$$Cost \: Price = \frac{Sell price *100}{100 + percentage\:loss}$$
Example
#include<iostream> using namespace std; float priceWhenProfit(int sellPrice, int profit) { return (sellPrice * 100.0) / (100 + profit); } float priceWhenLoss(int sellPrice, int loss) { return (sellPrice * 100.0) / (100 - loss); } int main() { int SP, profit, loss; SP = 1020; profit = 20; cout << "Cost Price When Profit: " << priceWhenProfit(SP, profit) << endl; SP = 900; loss = 10; cout << "Cost Price When loss: " << priceWhenLoss(SP, loss) << endl; }
Output
Cost Price When Profit: 850 Cost Price When loss: 1000
