WP queries optimization

Dear sir,

Please tell me where the below queries executed on WP site.

140 SELECT post_modified_gmt FROM wp_posts WHERE post_status = ‘publish’ AND post_type IN (‘post’, ‘page’, ‘attachment’, ‘xx’, ‘post types’, ‘all_site’) ORDER BY post_modified_gmt DESC LIMIT 1;

382 SELECT post_date_gmt FROM wp_posts WHERE post_status = ‘publish’ AND post_type IN (‘post’, ‘page’, ‘attachment’, ‘post types’,’guest-author’) ORDER BY post_date_gmt DESC LIMIT 1;
