| **It is known that each page of a document contains 128 lines containing 48 characters each. How many pages in the document, if its information volume, provided that each character was encoded with a 2-byte Unicode encoding, was 720 KB?**

First, let’s determine how many bytes of information are in the text. There are 1024 bytes in one kilobyte, therefore there are 737280 bytes in 720 Kbytes.

One character of the alphabet takes 2 bytes, therefore in the original text 737280: 2 = 368640 characters.

There are 48 characters in one line, so there are 368 640 lines in the text: 48 = 7680 lines.

One page contains 128 lines, so the total pages in the text: 7680: 128 = 60 pages.

Answer: the document you are looking for contains 60 pages of text.
