With the ratio from part A, we add up all the units to find that there are 40 units and it stands for 680 cakes.
Since the question is only asking for sponge cakes, we will narrow in to the sponge cake which is 15 units.
Giving away 40% will mean being left with 60% which is what the question is asking.
Therefore, just find out how many is 60% of the sponge cakes and you have your answer.
