In a library 5 per cent books are in English; 10 per cent of the remaining are in Hindi and 15 per cent of the remaining are in Sanskrit. The remaining 11628 books are in French. Then, find the total number of books in the library.
- A. 15000
- B. 12000
- C. 16000 ✓
- D. 10000
Correct Answer: C. 16000
Explanation
Let total books be x. Books remaining after English = 0.95x. After Hindi = 0.90 \times 0.95x. After Sanskrit = 0.85 \times 0.90 \times 0.95x = 11628. Solving gives x = 16000.
