No of cakes each parent has to bake : x/B
No of parents did not bake cake = p
No of cakes that were not baked by p parents = p*x/B
No of parents has to bake additional cakes = B-p
additional number of cakes that each of the other parents had to bake in order for the school’s request for x cakes = px/(B(B - P))
Answer B

If you pick numbers then the question is going to be easier:
X=100
B=10
P=5
100/10 = 10 cakes each on the first place
100/5 = 20 cakes after the number of parents were dropped
It results in a difference of 10 cakes.
The only answer that corresponds to this result is the letter B.
