Answer 1

75

Explanation:

Answer 2

There are 50 pages in the book.

Explanation:

Given that:

Martin has read 40% of the book.

Remaining percent = (100 - 40)% = 60%

Number of pages left to finish = 30

Let,

x be the total number of pages in the book.

60% of x = 30

`(60)/(100)x=30`

0.6x = 30

Dividing both sides by 0.6

`(0.6x)/(0.6)=(30)/(0.6)\\x= 50`

Hence,

There are 50 pages in the book.
