Check all Checkboxes checked in jQuery

My HTML Dom like the followings:

<div class="menu">
   <input type="checkbox" value="1" class="chk-act">
   <input type="checkbox" value="2" class="chk-act">
   <input type="checkbox" value="3" class="chk-act">
</div>


<div class="menu">
   <input type="checkbox" value="4" class="chk-act">
   <input type="checkbox" value="5" class="chk-act">
   <input type="checkbox" value="6" class="chk-act">
   <input type="checkbox" value="7" class="chk-act">
</div>



<div class="menu">
   <input type="checkbox" value="8" class="chk-act">
   <input type="checkbox" value="9" class="chk-act">
</div>

The number of Checkboxes is not fixed in each div. That can be 1 up to 50. So I need to check in each div if all checkboxes checked then some changes in div style like changed the color, what is your suggestion to check all checkboxes checked?

In one line:

$('.menu:has(:checkbox:not(:checked))');

To explain, this will select all the <div class="menu"> elements which have inside them a checkbox which hasn't been checked. You could then add a css class or do whatever you need. If you needed to 'reset' them after adding a class, I'd do something like this:

$('.menu')
    .removeClass('notChecked')
    .filter(':has(:checkbox:not(:checked))')
    .addClass('notChecked');
