I got 231, but apparently that's wrong. The answer is 230, but how do you get there?

Approximate total no of words for 120 pages at a mean of 231 gives (120*231) = 27720

Approximate total no of words for the first 20 pages at a mean of 236 gives (20*236) = 4720

Possible amount of remaining words in the remaining 100 pages are (27720-4720) = 23000

Therefore the mean of words per page for the remaining 100 pages is (23000/100) = 230
