Answer: Option A
Solution(By Examveda Team)
Let there are X books in the library. Number of Hindi books = 60% of X = $$\frac{{60{\text{X}}}}{{100}}$$ = 0.6X Remaining Books = X - 0.6X = 0.4X Number English books = 40% of reaming books = 60% of 0.4X = 0.24X. Urdu Books = X-0.6X -0.24X = 0.16X Given, 0.24X = 3600 X $$ = \frac{{3600}}{{0.24}} = 15000$$ Urdu Books = 0.16X = 0.16 × 15000 = 2400Join The Discussion
