    C) TFTF                          

    D) TTFF

    Correct Answer: A

    Solution :

         \[2x+3x=20\Rightarrow x=4\] Number of fiction books\[=2\times 4=8.\] Number of remaining kind of books \[=3\times 4=12.\] So, (A) is false and (C) is true. \[\frac{2}{3}=\frac{4}{6}=\frac{6}{9}\]; So. (B) is true and (D) is false.
