- Write a C program to read principal amount, rate of interest and time and calculate simple interest.
- Wap in C to find simple interest.

#### Required Knowledge

We will first read Principle amount, rate of interest and time using scanf function. We will use below mentioned formulae to calculate **Simple Interest (SI)**.

**Simple Interest = (Principle x Rate x Time) / 100**

## C program to calculate simple interest

/* * C program to calculate simple interest */ #include <stdio.h> int main() { float principle, rate, time, simpleInterest; /* * Take Principle, Rate of interest and * Time as input from user. */ printf("Enter Principle Amount\n"); scanf("%f", &principle); printf("Enter Rate of Interest\n"); scanf("%f", &rate); printf("Enter Time of Loan\n"); scanf("%f", &time); /* * Simple Interest = (Principle X Rate X Time)/100; */ simpleInterest = (principle * rate * time)/100; printf("Simple Interest = %.2f", simpleInterest); return 0; }

Output

Enter Principle Amount 10000 Enter Rate of Interest 5 Enter Time of Loan 2 Simple Interest = 1000.00
