<html>

<head>

function calc()

{

var consm, amount=0;

consm=document.form1.f1.value;

if(consm<=100)

amount=consm*1.0

else if(consm<=200)

amount=100+1.2*(consm-100)

else if(consm<=250)

amount=100+1.2*100+1.5*(consm-200)

else

amount=100+ 1.2*100 + 1.5*50 +2.0 *(consm-250)

document.write("amount payable is " + amount);

}
