  Units Charge
  ------------------------------------------------------
  0-200 Rs.0.50 per unit
  201-400 Rs.100 plus Rs.0.65 per unit excess 200
  401-600 Rs.230 plus Rs.0.80 per unit excess of 400.
  ------------------------------------------------------

• CODING ARENA

• #include <stdio.h>

  int main()

  {

    float  a; 

    scanf("%f",&a); 

    if(a<=200)

      {

      a=a*0.50;

    printf("Rs=%.2f",a); 

      }

    else if(a>200 && a<=400)

      {

      a=100+(a-200)*0.65;

      printf("Rs=%.2f",a);

      }

    else if (a>400 && a<=600)

      {

      a=100+130+(a-400)*0.80;

      printf("Rs=%.2f",a);

      }

  
  

  return 0;

  }
