Solution

The answer can be found by adding the percentages of students who failed in Science and Maths, and then subtracting the percentage of students who failed in both, because those students were counted twice.

So, the calculation is as follows:

15% (failed in Science) + 5% (failed in Maths) - 10% (failed in both) = 10% failed in either Science or Maths.

Therefore, the percentage of students who passed in both subjects is 100% - 10% = 90%.

However, 90% is not an option in the given choices. There might be a mistake in the question or the options provided.
