A field trip

A group of boys and girls went to a field trip. The total number of the kids was less than 15. If the number of girls in the group were 3 times larger, than there would be more girls than the boys. On the other hand, if the number of boys in the group were two times larger, than the number of boys would be larger than the five-fold number of girls.

Q1. How many girls were there on the field trip?

Q2. And how many boys?
