Calculate Simple Interest

Easy

308 upvotes

Problem statement

Take the principal amount, rate of interest, and the time period as input and calculate the Simple Interest.

Note: Return answer as Floor integer value.

Detailed explanation ( Input/output format, Notes, Images )

Input Format:

The first line of input contains a single integer Principal amount. 

The Second line of input contains a single decimal Rate of interest.

The Third line of input contains a single Integer Time period.

Output Format:

Calculate the Simple Interest and print it.

Sample Input 1:

2000
2.2
4

Sample Output 1:

Explanation of Sample Input 1:

The input is principal=2000, rate=2.2 and time=4.
So Simple interest=Principal*rate*time/100 hence 
answer is 2000*2.2*4/100=176

Approaches (1)

Approach 1

Using Simple Interest Formula

Take input of principal, rate and time respectively in three variables.

We can get the Simple interest by using the formula.

SI=(P* R * T)/100

Create a variable si and calculate it as above given formula and print it.

JAVA code using "type Cast" operator

import java.util.* ;
import java.io.*; 
class Solution {
	
	public static void main(String args[]) {
		
		Scanner sc = new Scanner(System.in);

		int principal = sc.nextInt();
		float rate = sc.nextFloat();
		int time = sc.nextInt();

		int simpleIntrest = (int) (principal*rate*time)/100;

		System.out.println(simpleIntrest);
		
	}
}

IN LINE NO.16

int simpleIntrest = (int) (principle*rate*time)/100;

here (int) is a type cast operator which is used to perform narrowing . ie. narrowing is process of storing the larger type of data into smaller type.

i.e. here float value of rate is converted into integer.
