Restaurant - Lucky Numbers Discount

Every day in a restaurant two numbers X and Y are considered lucky numbers.
If the bill amount B is divisible by X, then X% discount is offered.
If the bill amount B is divisible by Y, then Y% discount is offered.
If the bill amount B is divisible by both X and Y, then no amount is to be paid.

The program must accept X, Y and B and print the amount to be paid as the output (precision is up to 3 decimal places)

Input Format:
The first line contains B
The second line contains X
The third line contains Y

Output Format:
The first line contains the amount to be paid finally after discount.

Boundary Conditions:
1 <= X,Y <= 50
20 <= B <= 100000

Example Input/Output 1:

Output:

#include <stdlib.h>

int main()

{

int n,x,y;

scanf("%d\n%d\n%d",&n,&x,&y);

if(n%x==0 && n%y==0)

printf("%.3f",0);

else if(n%x==0)

printf("%.3f",(n-((n*x)*.01)));

else if(n%y==0)

printf("%.3f",(n-((n*y)*.01)));

else

printf("%.3f",(float)n);

}
