Solution
The correct option is B 7500
option (b)
We need to minimize the region of 2 and 3 areas of overlap, this means we need to maximize the region of only 1.
This can be shown in a conventional 3 set venn diagram as follows
For the area Kazakhstan
R&B= 75
Jazz=85
Country music =90
The value is thus 75% of 10000= 7500. Using the line technique discussed in the previous question, we can determine the answer much faster
