Answer 1

No, there are less than 90 people at the party.

Explanation:

This is because the number of women cannot go above 48 as it says "Some women leave".

-> This means that the ratio 10:11 actually states that there are 40 (or less) women and 44(or less) men in the party now which is less than 90 overall, so the answer is No.
