\([math]\left(x-\frac{1}{5}x-28\right)\left(1-\frac{7}{12}\right)=25\\ \left(\frac{4}{5}x- 28\right)\frac{5}{12}=25\\ \left(\frac{4}{5}x-28\right)=60\\ \frac{4}{5}x=88\\ x=110[/math]\)

Holt read 110 pages

Reading of 7/12 of the remaining pages on Wednesday means 5/12 of the remaining pages=25 pages

The remaining pages=25*12/5= 60 pages

Read 28 pages of the book on Tuesday=60+28=88

As read 1/5 of a book on Monday, 88 pages constitutes 4/5 of the book

Number of pages in the book=88/(4/5)=88*5/4=110 number
