My solution is the green triangle=6, the orange square=8, the yellow hexagon=7, the red circle=4 so the ?=21 I worked this out by trial and error. I started of on the bottom row with the circle=1 meaning the square=16 but that dosent work for the top row so I tryed still using the bottom row circle=2 meaning square=14 but that didnt work for the top row either so i went on to circle=3 meaning square=11 that did work for the top row but looking at the 3rd row down that means that triangle=9 witch doesn't work for the top row so i tryed circle=4 meaning square=8 and looking at the 3rd row down means triangle=6 and that works for the top row so that means hexagon=7 so i added 6,7,4 and 4 together to make 21 and that is how i got my solution
