Explanation:
Step1: Identify all parts of Venn - Diagram
The four parts of the Venn - diagram are: only tea (39), tea and coffee (45), only coffee (18), and neither tea nor coffee (10).
Step2: Calculate total number of people surveyed
Add all four parts together. So, (39 + 45+18 + 10). [39+45 = 84] [84+18=102] [102 + 10=112]
