5

Answer 2

5 pages

Step-by-step explanation:

Given: Ink in a pen lasts for 12 pages. Each page has 32 lines.

To find: 48 lines per page. How many pages will 1/2 pen ink last. There are 20% less letters than earlier case.

Solution:

Let's assume number of words per line = 100

Case 1, total words = 12 * 32 * 100

Case 2, total words = 48 * 80 * x where x is the number of pages.

Ink is half the pen.

So 12 * 32 * 100 / 2 = 19200

x = 19200 / (48* 80) = 5

So the 1/2 ink pen will last for 5 pages.
