Hello,

First off, I'd like to congratulate you guys for the awesome website.

I got a question regarding one word problem that has the following statement:

"Kamen read 2/3 of a book. He calculated that he read 90 pages more than the rest of it. How many pages does the book have?"

As you noticed, 2/3x is equal to 90 pages. Therefore, "x" is the total amount of pages the book has.

2/3x=90 => x=90/2/3=> x=135

To my surprise and dispair, the answer was 270. Below is the solution:

"If denote the total number pages by x, then he read 2/3.x

x-2/3.x=1/3.x is number of the rest of the book.

2/3.x-1/3.x=90 => 1/3.x=90 => x=270

So the book has 270 pages."

Thanks in advance,

Edielton
