Calculating total dividends for the year

Dear Mr Moffat,

This is a question from Kaplan’s F3 book.

A company has the following share capital:

—————————————-Authorised —- Issued
……………………………………$000…………..$000
25c ordinary shares……………8,000…………4,000
6% 50c preference shares……2,000…………1,000

In addition to providing for the year’s preference dividend, an ordinary dividend of 2c per share is to be paid before the year end. What are the total dividends for the year?

This is how I would calculate it:
Ordinary dividend = 2c x 4,000,000 = 80,000
Preference dividend = 0.06 x 1,000,000 = 60,000
Total = 140,000

However, this is the solution:
Ordinary dividends = 16,000,000 x 0.02 = 320,000
Preference dividends = 6% x 1,000,000 = 60,000
Total = 380,000

I really don’t understand why the solution uses $16,000,000 to get to the ordinary dividends…

Thank you in advance!
