if((a%5==0)&&(a+0.5<=b)&&(2000>=a>0)&&(0<b<=2000))
{
c=(b-a);
d=(c-0.5);
printf(“%f”,d);

This is wrong here .
c is an integer and but answer of b-a can be a decimal

Consider this test case

5 5.50
c = 0 in this but it should be 0.5

Your AC code 
#include <stdio.h>

int main(void) {
  int a, c;
  float b, d;
  scanf("%d %f", &a, &b);
  if ((a % 5 == 0) && (a + 0.5 <= b) && (2000 >= a > 0) && (0 < b <= 2000))
  {
// use d instead of c
    d = (b - a);
    d = (d - 0.5);
    printf("%.2f", d);
  }
  else
  {
    printf("%.2f", b);
  }
  return 0;
}
