Find amount of water wasted after filling the tank

Given the volume V of a tank in liter. There is a pump which is filling the tank at speed of M liter per minute. There is a leakage at the bottom of the tank which wasting water at speed N liter per minute. Given N is less than M. The task is to calculate how much amount of water will be wasted if leakage is seen after filling the full tank.
Examples:

Input : V = 700, M = 10, N = 3
Output : 300

Input : V = 1000, M = 100, N = 50
Output : 1000

Approach : Given the speed of filling pump is M liter per minute. So, the amount of water filled in one minute is M Liter. Also, N litres of water is wasted in a minute. Therefore after one minute the amount of water in the tank will be (M – N). Hence total time taken to fill the tank with leakage will be V / (M-N).
Therefore the amount of wasted water will be (V / (M-N)) * N.
Below is the implementation of the above approach: 

C++

// C++ program to find the volume of water wasted

#include <iostream>
using namespace std;

// Function to calculate amount of wasted water
double wastedWater(double V, double M, double N)
{
    double wasted_amt, amt_per_min, time_to_fill;

    // filled amount of water in one minute
    amt_per_min = M - N;

    // total time taken to fill the tank
    // because of leakage
    time_to_fill = V / amt_per_min;

    // wasted amount of water
    wasted_amt = N * time_to_fill;

    return wasted_amt;
}

// Driver code
int main()
{
    double V, M, N;
    V = 700;
    M = 10;
    N = 3;
    cout << wastedWater(V, M, N) << endl;

    V = 1000;
    M = 100;
    N = 50;
    cout << wastedWater(V, M, N) << endl;

    return 0;
}

Java

// Java program to find the
// volume of water wasted
class GFG
{

// Function to calculate amount of wasted water
static double wastedWater(double V, double M, double N)
{
    double wasted_amt, amt_per_min, time_to_fill;

    // filled amount of water in one minute
    amt_per_min = M - N;

    // total time taken to fill the tank
    // because of leakage
    time_to_fill = V / amt_per_min;

    // wasted amount of water
    wasted_amt = N * time_to_fill;

    return wasted_amt;
}

// Driver code
public static void main(String[] args)
{
    double V, M, N;
    V = 700;
    M = 10;
    N = 3;
    System.out.println(wastedWater(V, M, N)) ;

    V = 1000;
    M = 100;
    N = 50;
    System.out.println(wastedWater(V, M, N));
}
}
