Wonderlic test question?

Question

I've just stumbled past a Wonderlic test question. This one:

 In printing an article of 48,000 words, a printer decides to use two sizes of type. Using the larger type, a printed page contains 1,800 words. Using smaller type, a page contains 2,400 words. The article is allotted 21 full pages in a magazine. How many pages must be in smaller type?

The official answer is 17. Can somebody explain me why that is? How come? If he's got 21 pages, he can fill 20 with the larger type and still has an empty page. Ideas, anyone?

48,000 words divided by 1800 large words/page = 26.67 pages, not 20.

L=large type pages
S=small type pages

1800L+2400S=48000
L+S=21

Solving for S gives 17 small-type pages.

Bense - You've just got your numbers mixed up in the equation you did.  Instead of multiplying the 17 pages by 1,800, you should be multiplying it by 2,400, since you're talking about the small-type pages.

It's easy once you plug in the numbers:

17 small pages at 2,400 words each = 40,800
4 large pages at 1,800 words each = 7,200

Total =48,000

If you use 17 smaller type pages, you calculate 17*2400.
You will use 4 larger type pages, you calculate 4*1800.

17*2400 = 40,800 words
4*1800 = 7,200 words

40,800 + 7,200 = 48,000 words & 21 pages exactly.

You are over-analyzing. They just want to test your math skill.
