Amsar ita ce 50. <eng> Gwendolyn just brought a book from the library, having 20 paragraphs per page, and since the book has 50 pages, the number of paragraphs in the book is 50 * 20 = 1000 paragraphs. If each paragraph has 10 sentences, the book's number of sentences is 1000 * 10 = 10000 sentences. Since Gwendolyn can read 200 sentences of a book in 1 hour, she will read 10000 sentences in 10000 / 200 = 50 hours. So the answer is 50.
