Answer:

75%

Step-by-step explanation:

The 10% that failed both is part of the 15% and 20% that is mentioned. Subtract 10% from each, leaving you with 5% that failed just science, 10% that failed just math, and 10% that failed both. Add them together and you get 25%. Subtract 25% from 100%, and you remain with 75%.
