Thank you @hunio,

Your code works very good.

I also make small updates and if I want to share edited version maybe someone want to use this type of output.

My output is like given below;

<script src="https://domain.com/wp-content/cache/minify/30d40.js?ver=2.1.5"></script>
<link rel="stylesheet" href="https://domain.com/wp-content/cache/minify/5d995.css?ver=2.1.5" media="all" />

My Code is like given below;

function w3tc_filename_filter($minify_filename, $files, $type ){
    
    $themes_version = wp_get_theme()->get('Version');

    $minify_filename = $minify_filename . '?ver=' . $themes_version;
    return $minify_filename;
}
add_filter('w3tc_minify_urls_for_minification_to_minify_filename', 'w3tc_filename_filter', 20, 3);
