In a library, 20% books are in Hindi, 50% of the remaining are in English and the remaining 9000 are in other languages. Total books are:
A18000
B22500
C25000
D30000
✓ Correct Answer: B — 22500
Remaining after Hindi = 80%. English = 50% of 80% = 40%. Other = 80% - 40% = 40%. 40% = 9000, so 100% = 22500.
