currently i am reading that book.But it seems as though i can't even solve one question from it despite of me reading and understanding each and every line of the chapter.what to do?

I find that hard to believe. Many of the questions are routine. Can you post examples?
Try to solve by componendo dividendo proportion 19 examples 2 #13

$$\frac{2x^3-3x^2+x+1}{2x^3-3x^2-x-1}=\frac{3x^3-x^2+5x-13}{3x^3-x^2-5x+13}$$
