out of 7500 candidates 75% offered english and 45% offered maths.how many offered both?

20 percent

To find out how many candidates offered both English and Math, we need to use the concept of overlapping sets and find the intersection between the two sets.

Given that 75% of candidates offered English and 45% offered Math, we cannot directly calculate the number of candidates who offered both subjects using only the given percentages. We need to know the total number of candidates or the specific number of candidates who offered only one subject to calculate the overlapping number.

If we have additional information, such as the total number of candidates or the number of candidates who offered only one subject, we can proceed with the calculations. Please provide any further details if available.
