This one was a little harder, the solution was tricky for sure! As always not going to reveal any solutions for these, it’s just to satisfying to do these by hand and see the solution with a big rush of relief. I wouldn’t rob anyone of the challenge.

C, highest row 4 black + 8 red middle row 6 black + 6 red lowest row probably 8 black + 4 red
left column 4 black + 8 red middle column 6 black + 6 red right column probably 8 black + 4 red
diagonal1 6+6 diagonal2 6+6

When looking at the shapes only, there are 3 of each kind so the answer is either c or d. When only looking at the colors of the inner shapes, there are no inner shapes having another inner shape to the left right above or below with the same color wich rules out d.
c is the answer

Set X to half of what Mia can do in a day, then in one day Mia can do 2X and Emily 3X, for a daily total between them of 5X; the total task, which takes both of them 24 days, is 120X. Working alone, then, Mia could do it in 60 days or Emily in 40.

Emily does 3/5 of the work in 24 days, so it would take her 40 days to do the whole. Mia does 2/5 of the work in 24 days, so it would take her 60 days to do the whole.
