Each of the questions below consists of a question and two statements marked P and Q given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and: Give answer:
A library contains only English, Hindi and Telugu novels. How many Telugu novels are there in the library?
P. Of the one thousand novels is the library, fifty per cent novels are in English and Hindi.
Q. The number of Hindi novels is double the number of English novels.
Solution
Let us test each statement and see whether we can get the number of Telugu novels.
1. There are only three types of novels, and of the one thousand novels is the library, fifty percent novels are in English and Hindi. This means that the remaining 500 books are Telugu novels.
2. Even after knowing that Hindi novels are double in number than English novels, we have no clue about the exact number of any of these categories. Hence, we can't find the number of Telugu novels from this data.
