 <translate> Since Darryl has 20 books, Lamont, who has twice the number of books Darryl has, has 20 * 2 = 40 books. The total number of books both Darryl and Lamont has is 40 + 20 = 60 books. To have the same number of books as Lamont, Loris needs 3 more books, meaning she has 40 - 3 = 37 books. In total, the three has 60 + 37 = 97 books.
