• A. 3400
• B. 3500
• C. 3100
• D. 3200
• E. None of these

Answer 1

The correct option is D 3200

Let there are X books in the library
Hindi books = 60% of X = $\frac{60X}{100}=0.6X$
Remaining Books = X - 0.6X = 0.4X
English books = 60% of remaining books = 60% of 0.4 X $=\frac{60\left(0.4X\right)}{100}=0.24X$
Malayalm Books = X - 0.6X - 0.24X = 0.16X
Given, 0.24X = 4800 $\Rightarrow$ X = $\frac{4800}{0.24}=20000$
Malayalam Books = 0.16X = 0.16$\times$20000 = 3200
