• 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)*0.8+230;

    else cost=390;

    printf("Rs=%0.2f",cost);

    

  
  

  return 0;

  }
