给定标价

和售价为

产品。任务是计算应用于该产品的折扣百分比。

例子:

Input: M = 120, S = 100
Output: 16.66%

Input: M = 1000, S = 500
Output: 50%

推荐：请尝试以下方法{IDE}首先, 在继续解决方案之前。

计算产品折扣率的数学公式为：

Discount = Marked Price - Selling price

Therefore, Discount Percentage = (Discount / Marked Price) * 100

以下是查找产品折扣百分比的程序：

C ++

// CPP Program to find the Discount Percentage
  
#include <bits/stdc++.h>
using namespace std;
  
// Function to find the Discount Percentage
float discountPercentage( float S, float M)
{
     // Calculating discount
     float discount = M - S;
  
     // Calculating discount percentage
     float disPercent = (discount / M) * 100;
  
     return disPercent;
}
  
// Driver code
int main()
{
     int M, S;
     M = 120;
     S = 100;
      
     // Setting the precision to 2 decimals
     cout << std::fixed << std::setprecision(2)
         << discountPercentage(S, M) << "%" << endl;
  
     M = 1000;
     S = 500;
      
     // Setting the precision to 2 decimals
     cout << std::fixed << std::setprecision(2)
         << discountPercentage(S, M) << "%" << endl;
  
     return 0;
}

Java

// Java Program to find the Discount Percentage
  
import java.util.*;
import java.lang.*;
import java.io.*;
  
class GFG{
   
// Function to find the Discount Percentage
static float discountPercentage( float S, float M)
{
     // Calculating discount
     float discount = M - S;
   
     // Calculating discount percentage
     float disPercent = (discount / M) * 100 ;
   
     return disPercent;
}
   
// Driver code
public static void main(String args[])
{
     int M, S;
     M = 120 ;
     S = 100 ;
  
     System.out.printf( "%.2f" , discountPercentage(S, M));
     System.out.println( "%" );
      
   
     M = 1000 ;
     S = 500 ;
  
    System.out.printf( "%.2f" , discountPercentage(S, M));
     System.out.println( "%" );
}
}

Python3

# Python3 Program to find the 
# Discount Percentage
  
# Function to find the 
# Discount Percentage
def discountPercentage(S, M):
  
     # Calculating discount
     discount = M - S
  
     # Calculating discount percentage
     disPercent = (discount / M) * 100
  
     return disPercent
  
  
# Driver code
if __name__ = = '__main__' :
     M = 120
     S = 100
  
     print (discountPercentage(S, M), "%" )
  
     M = 1000
     S = 500
  
     print (discountPercentage(S, M), "%" )

     M = 120;
     S = 100;
  
     Console.Write(discountPercentage(S, M));
     Console.WriteLine( "%" );
      
     M = 1000;
     S = 500;
  
     Console.Write(discountPercentage(S, M));
     Console.Write( "%" );
}
}

的PHP

<?php
// PHP Program to find the 
// Discount Percentage
  
// Function to find the 
// Discount Percentage
function discountPercentage( $S , $M )
{
     // Calculating discount
     $discount = $M - $S ;
  
     // Calculating discount percentage
     $disPercent = ( $discount / $M ) * 100;
  
     return $disPercent ;
}
  
// Driver code
$M ; $S ;
$M = 120;
$S = 100;
  
echo discountPercentage( $S , $M ), "%" , "\n" ;
  
$M = 1000;
$S = 500;
  
echo discountPercentage( $S , $M ), "%" , "\n" ;
  
// This code is contribute 
// by inder_verma
?>

输出如下：

16.67%
50.00%
