    Answer:

    180

    Step-by-step explanation:

    Let, the total number of pages be x.

    A/Q,

    x -  \frac{8}{9} x = 20 \\  =  > x -  \frac{8x}{9}  = 20 \\  =  >  \frac{9x - 8x}{9}  = 20 \\  =  >  \frac{x}{9}  = 20 \\  =  > x = 20 \times 9 \\  =  > x = 180

    Therefore, there are total 180 pages in the book.
