Got B. I quite like drawing trees for these type of questions. Allows me to visualize things much easier.

We know 10 toys are red and size a out of 100. Moving up the tree, we can find out that overall 25 toys are red, because 25% of toys are red, and 25% of 100 is 25. That leaves 15 red and size B

Moving to the blue side, overall we must have 25 blue. Since 50% of toys are size b, and we already have 15 size b of red, we need size b red + size b blue = 50, and 50-15=35
