Answer 2

Since 1 page contains 120 words.
therefore, 400 page contain (120 * 400) words.
➡ 120 * 400 = 48000 words.

No of words contained in the book = 48000.

Now A/Q,
150 words are printed on 1 page.
therefore, 48000 words will be printed on (1/150) * 48000
➡ 320 pages.

Hope it will help you !!!
