How to Limit the paginate in cakephp ?

Assume that i have 400 records.
I need to get only 25 records from 50th record to 75th record and need to display 5 records per page.
How i can do this in paginate ?

Sample Code:

        $this->paginate = array(
                'contain'=>array('User'),
                'recursive' => 2,
                'order' => array('Profile.winning' => 'DESC'),
                'limit' =>5

            );
