Answer 2

Answer:

There are 50 pages in the book.

Step-by-step 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

$\frac{60}{100}x=30$

0.6x = 30

Dividing both sides by 0.6

$\frac{0.6x}{0.6}=\frac{30}{0.6}\\x= 50$

Hence,

There are 50 pages in the book.
