从给定的销售价格和损益百分比中找到成本价格

给定产品的售价(SP)和损益百分比。任务是计算产品的成本价格(CP)。

例子：

Input:  SP = 1020, Profit Percentage = 20
Output: CP = 850

Input: SP = 900, Loss Percentage = 10
Output:  CP = 1000

方法：

• 如果给出销售价格和利润百分比，则计算成本价格的公式：

  CP = ( SP * 100 ) / ( 100 + percentage profit).

• 如果给出销售价格和损失百分比，则计算成本价格的公式：

  CP = ( SP * 100 ) / ( 100 – percentage loss ).

以下是所需的实现：

C++

// C++ implementation to find Cost price
#include 
using namespace std;
  
// Function to calculate cost price with profit
float CPwithProfit(int sellingPrice, int profit)
{
    float costPrice;
  
    // required formula to calculate CP with profit
    costPrice = (sellingPrice * 100.0) / (100 + profit);
    return costPrice;
}
  
// Function to calculate cost price with loss
float CPwithLoss(int sellingPrice, int loss)
{
    float costPrice;
  
    // required formula to calculate CP with loss
    costPrice = (sellingPrice * 100.0) / (100 - loss);
    return costPrice;
}
  
// Driver code
int main()
{
    int SP, profit, loss;
  
    SP = 1020;
    profit = 20;
    cout << "Cost Price = " << CPwithProfit(SP, profit) << endl;
  
    SP = 900;
    loss = 10;
    cout << "Cost Price = " << CPwithLoss(SP, loss) << endl;
  
    SP = 42039;
    profit = 8;
    cout << "Cost Price = " << CPwithProfit(SP, profit) << endl;
  
    return 0;
}
