    A boy read 3/4 of pages on Monday,

    4/5 of the remaining pages on Tuesday,

    Carefully observe that he gave he read 4/5 of remainder pages on Tuesday ; which means that 1/5 is left of the remaining pages, that 1/5 is 30 pages.

    So , the 4/5 of remaining  pages are = 30 x4 = 120 pages,

    and the total remaining are = 5/5 = 30 x 5 = 150 pages are the remaining pages.

    And first, he gave that he read 3/4 of the book, which means that  the remaining 1/4 = 120 pages ;

    then the 3/4 pages  = 3 x 120

    So, The pages he read on Monday = 360 pages ;

    So the total pages = 360[ Monday ] + 120[Tuesday + remaining pages] pages ;

    Total pages = 480 pages

    So the book has 480 pages in total.
