C program for "If the total selling price of 15 items and the profit earned on them is input through the keyboard, write a program to find the cost price of 1 item."

Problem: C program for "If the total selling price of 15 items and the profit earned on them is input through the keyboard, write a program to find the cost price of 1 item."

Logic used : 

• Subtract profit from selling price and divide by 15
• Store the result in a variable
• Print that variable

Demo :

cost price = ( selling price - profit ) / 15

C program :

// Program by Shyam kanth

#include<stdio.h>

int main(){

    int sp,profit;

    float cp;

    printf("Enter the selling price of all 15 items : ");

    scanf("%d",&sp);

    printf("Enter the profit earned on them : ");

    scanf("%d",&profit);

    cp=(sp-profit)/15;

    printf("The cost price of one item is %.2f.",cp);

    return 0;

}

Codes used : 

• #include < stdio.h > : Header file for input-output
• int : Integer data type
• sp, cp, profit : Variable used
• printf : Function for displaying message
• scanf : Function for taking input
• %d : Format specifier for integer type data
• %f : Format specifier for decimal data
