Answer:
Explanation:
52 predicted that they will pass which means that (80-52) = 28 predicted that they will fail.
people who passed among the predicted ones = 52 * 3/4 = 39 people
54 people pass altogether so people who passed among the ones who predicted they will fail = 54 -39 = 15 people
percentage = 15/28 * 100 = 53.6 %
