A sample of 1,006 customers were polled at a chain grocery store and asked to identify what major soda brand they purchase most often. The pie chart shows the percentage of respondents who preferred each brand. Their choices were limited to Pepsi, Coke, 7-UP, Dr Pepper, and generic soda. Select the best answer to fill in the blanks in each of the statements based on the data shown in the Pie chart.

Suppose, Total customers = 100

Pepsi buyers = 38

therefore, required % = 38/41 = 92.7 % = 93% (approx)

93 is the correct answer



B. Out of the customers surveyed, the total number who bought either 7-UP or Dr Pepper is closest to ___________.

the total number (in % terms) who bought 7-UP = 15%
the total number (in % terms) who bought Dr Pepper = 2%
