If the sum of two pages is 19 and the sum of the next is 2, what page was I reading?

I noticed that the sum of the digits of the number on the page I was reading was 19, and the sum of the next digits on the page was 2. What was the number of the page I was reading?

The two pages you were reading were pages: 99 and 100.

9 + 9 + 1 + 0 + 0 = 19

The next page is: 101.

1 + 0 + 1 = 2

Therefore you were reading page 100 because the NEXT page must be page 101.

The confusion is with the presentation of the question.  Both Nataliya and Andrew are right, and both a little wrong.  Emilia from Chino first says that the sum of the digits from TWO pages was 19 (heading in green), but then asserts a single page in the text.  There is no correct answer possible, as the student presents two different questions whose answers are exclusive.  Both tutors realized the problem ran to the 99, x00 moment, but each should have recognized the impossibility of providing a single correct answer.  Andrew misses in that 100 does not satisfy the conditions in the text part of the question, and Natalya avoids the assertion in the heading that 2 pages, not one, are involved.  However, Andrew stretches further than Natalya in that he apparently believes two pages can be read simultaneously.  I wish that both tutors had rejected the question as unanswerable rather than provide solutions which satisfied no one.

You were reading page number 199
pg 199: 1 + 9 + 9 = 19 and next page is 200: 2 + 0 + 0 = 2

The sum of TWO pages. Page 199 is just ONE page, which makes this answer incorrect. It then goes on to say the next page, which is in addition to the first two previous pages, equalling THREE page numbers you should be including in your equation. If you see Andrew's response above, it makes more sense. 

Actually, I answered on the second question "I noticed that the sum of the digits of the number on the page I was reading was 19, and the sum of the next digits on the page was 2. What was the number of the page I was reading?" That's way I started with "You were reading page ..."
And Andrew answered on first question ....
