How many odd pages are there in a book 479 pages long?

Answer 1

240

This is a way to see how this was calculated ...
If 1 page has 1 odd page,
and 3 pages has 2,
and 5 pages has 3,
and 7 pages has 4,
then all we have to do is add 1 to the maximum number and divide by 2.

Try it on the above numbers and check your results.

When you are satisfied that it works, try it ..
479 + 1 = 480.
480 divided by 2 = ?
