考虑我们有售价,并给出了损益的百分比。我们必须找到产品的成本价。公式如下-
$$Cost \:价格= \ frac {卖出价格* 100} {100 +百分比\:利润} $$
$$Cost \:价格= \ frac {卖出价格* 100} {100 +百分比\:亏损} $$
#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;
}输出结果
Cost Price When Profit: 850 Cost Price When loss: 1000
