Answer 1

As additional to @Karthick Kumar answer from bootstrap docs

show is triggered at the start of an event

shown is triggered on the completion of an action

... so it should be:

$('.modal')
    .on('show.bs.modal', function (){
            $('body').css('overflow', 'hidden');
        })
    .on('hide.bs.modal', function (){
            // Also if you are using multiple modals (cascade) - additional check
            if ($('.modal.in').length == 1) {
                $('body').css('overflow', 'auto');
            }
        });
