Study the following information carefully and answer the question given below. Six books B, C, D, F, N and V contain different numbers of pages and are arranged in descending order from the left end according to the number of pages. Book N contains the least number of pages, which is an odd prime number less than 7. The number of books between book N and book F is the same as the number of books between book C and book F. Book B contains just fewer pages than book F, which contains thrice the number of pages in book N. The book which contains just more pages than book V contains a number of pages equal to the square of the number of pages in book N and book F. The book which contains 150 pages does not contain the maximum number of pages. What is the total number of pages in books V and F?
- 65 pages
- 52 pages
- 55 pages
- 165 pages
Correct answer: 165 pages
Solution
N must be 5, since it is the least odd prime less than 7. Then F = 3 × 5 = 15, and the square relation gives 25 for the book just above V. From the arrangement, V is 150 pages, so V + F = 150 + 15 = 165.
