Check another checkbox automatically inside loop

I am trying to do one new thing i.e. when i check one checkbox another checkbox will be checked automatically. I have two checkbox in each row i.e. it is in loop.

Here is my full code :

<?php 
include("config.php");

$sql="SELECT * FROM inventory_details where status ='0' AND role='0' ORDER BY position ASC, role ASC, visiter DESC limit 0,100";    
$query=mysqli_query($conn, $sql);

?>
<form method="post" action="" id="msform">  
  <div class="container">
      <div class="row invent_det cate_head">
        <div class="col-md-1 "><strong>Select </strong></div>
        <div class="col-md-1 "><strong>Select </strong></div>
      </div>

      <?php
        $i=0;
        $today_date=date("Y-m-d H:i:s", time()); 
        while($row=mysqli_fetch_assoc($query)){
        $id = $row['id'];
        $catagory_name = $row['catagory_name'];
        $PrimaryMobile_no = $row['PrimaryMobile_no'];
      ?>

      <div class="row" style="background-color: <?php echo $inventorybackground; ?> !important; color: <?php echo $inventorycolor; ?>; padding-top: 10px;">

        <div class="col-md-1 inventory-data">
          <input type="checkbox" id="checkItem" name="firm_name[]" value="<?php echo $firm_name;?>-<?php echo $PrimaryMobile_no;?>">
        </div>

        <div class="col-md-1 inventory-data">
          <input type="checkbox" id="checkItem" name="check[]" value="<?php echo $row["id"]; ?>">
        </div>
      </div>
<?php
$i++;
}
?>

  </div>
</form>

I have already tried some examples but failed to do so. I have implemented these https://jsfiddle.net/Bhawesh7731/4jsbLedn/

but when i check one checkbox, all the checkbox are checked automatically and i don't want that. I only want that, when i check the checkbox another checkbox of that row will be checked.
