In this tutorial, we will be discussing a program to find the rate percentage from compound interest of the consecutive years.For this, we will be provided with two integers say A and B that are the interests of two consecutive years. Our task is to find the rate of interest for the given values.Finding the relation between the given values and eliminating the principal amount, we get the formula asrate = ((B-A)*100)/AExample#include using namespace std; //calculating the rate of interest float calc_rate(int N1, int N2) {    float rate = (N2 - N1) * 100 / float(N1);    return ...

In this tutorial, we will be discussing a program to find the quantity of milk left after mixture replacement.Let us suppose we have X litres of milk. From that, Y litres of milk is replaced with Y litres of water itself. This same procedure is done again and again Z number of times. Our task is to find the final amount of milk left in the container.Finding the relation among the values between the repetitive operations, we find the formula for finding the amount of milk after Z number of operations to beamount left = ((X-Y)/X)Z*XExample#include using namespace std; ...
