Q1: The answer is 5 brownies
Frist I figured out that when there were 7 brownies left in the first plate, and 3 were taken, i added and got the result of 10. And it said that the total of 2 plates were 15. So i subtracted 15-10 and got 5

There were 15 cookies. 3 were taken away which left 7 on that plate. Before the cookies were taken away there were 10, so there had to be 5 on the other plate.
