Answer 1

=> is wrong syntax.
Use >=

Edit :

not mention %, you can use in output statements.
Check out changes in code..

//

<?php
$marks=100;
if ($marks < 35){
echo 'fail';
}
elseif($marks>=35 && $marks<=50){
echo'B grade';
}
elseif($marks>=50 && $marks<=75){
echo'A grade';
}
elseif($marks>=75 && $marks<=100){
echo 'A++ grade';

}
?>
