Look carefully at the sections of the Venn diagram that correspond to the specific groups you are being asked about. This will help isolate the relevant numbers.
The number of educated rural people who are employed but not hardworking is 12. This can be seen in the Venn diagram where the segment representing educated rural people who are employed (without overlapping with the hardworking area) contains the number 12.

Question: 2
How many hardworking educated persons are either employed or from the rural area but NOT both?
Show Hint
When asked for people in one category but not both, look for the sections of the diagram that represent the exclusive parts of the categories involved.
The number of hardworking educated persons who are either employed or from the rural area but NOT both is 13. This is found in the Venn diagram by adding the values from the hardworking section that are either employed or belong to the rural area, but not both.
