There is a very wonderful book in the ancient bookstore, with a total of 200 pages. Mr. A bought it. When watching, Mr. A first removed the 10 pages from the 3rd to the 12th pages that he was interested in, leaving 190 pages. Later, he removed 20 pages from page 56 to page 75. Excuse me, how many pages are left in this book?
