Question
In the given Venn diagram, the rectangle 'people having
blue eyes', the triangle represents 'people having extra fingers', and the circle represents 'people having dimples'. The number of people who have extra fingers and blue eyes and no dimples is A and if the number of people who have extra fingers and dimples and no blue eyes is B. What is the sum of A and B?Solution
The number of people who have extra fingers and blue eyes and no dimples is A = 28 The number of people who have extra fingers and dimples and no blue eyes is B = 15 Required sum = 28 + 15 = 43
