Answer 1

Answer:

75 pages

Step-by-step explanation:

3/5 pages read

2/5 books are not read =30 pages

read pages 45

45+30=75

Answer 2

The book contained 75 pages.

Step-by-step explanation:

Consider total number of pages in the books are x,

Given,

The part of book has read = $\frac{3}{5}$

Remaining part of the book that unread = $1-\frac{3}{5}$

$=\frac{5-3}{5}$

$=\frac{2}{5}$

According to the question,

$\frac{2}{5}\text{ of total pages}=30$

$\frac{2x}{5}=30$

$2x=150$

$\implies x =\frac{150}{2}=75$

Hence, the book contained 75 pages.
