Q11) A showroom gives discount according to the following slab rates on the purchase amount.

 Purchase Amount Discount Up to 5,000 No Discount 5,001 to 10,000 10% of the amount exceeding 5000 10,001 to 20,000 20% of the amount exceeding 10,000 20,001 to 30,000 30% of the amount exceeding 20,000 More than 30,000 40% of the amount exceeding 30,000

Write a program in C to input the purchase amount and print the discount amount and the net bill amount after deducting the discount amount.

#### Program

``````#include <stdio.h>
#include <conio.h>

int main()
{
int p;
float dis;
printf("Enter purchase amount ");
scanf("%d",&p);

if(p<=5000)
{
dis=0;
}
else if(p>5000 && p<=10000)
{
dis=(p-5000)*(10/100.0);
}
else if(p>10000 && p<=20000)
{
dis=(p-10000)*(20/100.0);
}
else if(p>20000 && p<=30000)
{
dis=(p-20000)*(30/100.0);
}
else
{
dis=(p-30000)*(40/100.0);
}

printf("Discount Amount = %.2f\n",dis);
printf("Net Bill Amount = %.2f\n",p-dis);
return 0;
}``````

#### Output

```Enter purchase amount 25648
Discount Amount = 1694.40
Net Bill Amount = 23953.60```
