Question

Write an algorithm to enter principle, rate and time. Calculate the simple interest.

Answer 1

SI=P×R×T/100

Required knowledge

Arithmetic operators, Variables and expressions, Data types, Basic input/output

Simple Interest formula

Simple interest formula is given by.

Where,

P is the principle amount

T is the time and

R is the rate

Logic to calculate simple interest

Step by step descriptive logic to calculate simple interest.

Input principle amount in some variable say principle.

Input time in some variable say time.

Input rate in some variable say rate.

Find simple interest using formula SI = (principle * time * rate) / 100.

Finally, print the resultant value of SI.

Program to calculate simple interest

/** * C program to calculate simple interest */ #include <stdio.h> int main() { float principle, time, rate, SI; /* Input principle, rate and time */ printf("Enter principle (amount): "); scanf("%f", &principle); printf("Enter time: "); scanf("%f", &time); printf("Enter rate: "); scanf("%f", &rate); /* Calculate simple interest */ SI = (principle * time * rate) / 100; /* Print the resultant value of SI */ printf("Simple Interest = %f", SI); return 0; }
