Try to rephrase your problem. This makes no sense.

Not sure if this helps but this is what I get from your question.

```
<?php
$testnumbers = array("5240","7000","7142","11000","21050");
//Test Single Number
//$roll_number = "5240";
$ninth_roll_numbers = array();
foreach(range(1,6702) as $num){
$ninth_roll_numbers[] = $num;
}
foreach(range(7101,7152) as $num){
$ninth_roll_numbers[] = $num;
}
foreach(range(20001,103090) as $num){
$ninth_roll_numbers[] = $num;
}
//run a little test with array $testnumbers
foreach ($testnumbers as $roll_number){
$total_marks = (in_array($roll_number,$ninth_roll_numbers) ? 525 : 1050);
echo "Total Marks: $total_marks<br />";
$percent = $roll_number/$total_marks;
echo "Result: $percent<br /><br />";
}
?>
```

This comes out as

Total Marks: 525

Result: 9.9809523809524

Total Marks: 1050

Result: 6.6666666666667

Total Marks: 525

Result: 13.60380952381

Total Marks: 1050

Result: 10.47619047619

Total Marks: 525

Result: 40.095238095238

Could also do it with a bunch of IF greater than && less than statements but I like working with arrays.

```
echo "TEST Two<br />";
$testnumbers = array("5240","7000","7142","11000","21050");
//run a little test with array $testnumbers
foreach ($testnumbers as $roll_number){
if (
($roll_number>=1 && $roll_number<=6702) ||
($roll_number>=7101 && $roll_number<=7152) ||
($roll_number>=20001 && $roll_number<=103090)
){
$total_marks = 525;
}else{
$total_marks = 1050;
}
echo "Total Marks: $total_marks<br />";
$percent = $roll_number/$total_marks;
echo "Result: $percent<br /><br />";
}
```

Results are the same.
