    D Data is inadequate Correct Answer Incorrect Answer

    Solution

    Statement 1: The book has 300 pages, out of which two-thirds were read by her before Sunday. Two-thirds of 300 = 200 pages read before Sunday That means 100 pages remained starting Sunday onward But we don’t know how many pages she read on Sunday specifically, or how many were left for Monday. Statement 1 alone is not sufficient.   Statement 2: Sania read the last 40 pages of the book on the morning of Monday. So, out of the total pages, the last 40 pages were read after Sunday. We don’t know how many pages she had read before Monday unless we know the total number of pages. Statement 2 alone is not sufficient Combine Statement 1 and 2: From Statement 1: 300 total pages, 200 read before Sunday, so 100 pages left starting Sunday. From Statement 2: 40 pages were read on Monday So the rest (100 - 40 = 60 pages) were read on Sunday Final Answer: Both Statement 1 and Statement 2 are sufficient Because together they let us calculate that Sania read 60 pages on Sunday. Correct option: Both Statement 1 and Statement 2 are sufficient.
