  Tom want to know about the calculation of electricity charges. Explain him about the calculation by using C code to reads the customer number and power consumed and prints the amount to be paid by the customer.Consumption Rate of
  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()

  {

    int uni;

    float cost;

    scanf("%d",&uni);

    if(uni>0&&uni<=200)

      cost=uni*0.5;

    else if(uni>200&&uni<=400)

      cost=(uni-200)*0.65+100;

    else if(uni>400&&uni<=600)

      cost=(uni-400)*0.80+230;

    else cost=390;

    printf("Rs=%0.2f",cost);

  
  

  return 0;

  }
