Almost forgot about this thread. Here goes:

Find the number w with the help of the following sentences:

1.At least one of the sentences 9 and 10 are true.
2.This is either the first true or the first false sentence.
3.There are 3 successive false sentences.
4.The difference between the numbers of the last true sentence and the first true sentence devides w exactly. (eg. 2 devides 10 exactly)
5.w is the sum of the numbers of all the true sentences.
6.This is not the last true sentence.
7.The number of every true sentence devides w exactly.
8.w is the percentage (%) of all true sentences.
9.The quantity of the positive numbers that devide w exactly (excluding/without 1 and w) is greater than the sum of the numbers of all true sentences.
10.There aren't 3 successive true sentences.
