Explanation:

- The problem provides the following information:

- 48% of candidates passed in science.

- 56% failed in mathematics.

- 32% of candidates failed in both subjects.

- We wish to determine the percentage of candidates who passed both subjects.

- Use the formula: Passed both = Passed science + Passed math - Passed either (Total).

- Candidates who passed science = 48%, so failed science = 52%.

- Candidates who failed both subjects are part of those who failed math (since 56% failed math).

- Those who failed only math = 56% - 32% = 24%.

- Candidates who passed math = 100% - 56% = 44%.

- Passed in both = Total candidates - failed science - failed only math = 100% - 52% - 24% = 24%.

- So, the percentage of candidates who passed in both subjects is 24%.

- Correct Option: Option 3: 24%
