Answer 1

Answer:

Let the total of pages in the book be X

=> x - 2x /3 = 27

=> 3x - 2x /3 = 27

=> x /3 = 27

=> x= 27 x 3

=> x = 81

Answer 2

AnSwer:

Let the pages present in books be x.

★ According to the question,

• 2/3 of x are 27 pages

$\longmapsto \sf \:$ 2x/3 + x = 27

$\longmapsto \sf \:$27= x - 2x/3

$\longmapsto \sf \:$27 = x/3

$\longmapsto \sf \:$x = 81 page's

So, there are 81 pages in book.
