Question

George records the number of questions he has answered on DFM per day over 14 days, and puts the data in the bar chart below.

Find the total number of questions.

Answer 1

18 is the total number of questions George answered in 14 days.

Explanation:

The given chart:

• The x-axis is showing the total number of questions George answered

• The y-axis is showing the frequency of days on which George answered the questions.

The given chart is showing that:

• George answered the 5 questions on the first 4 days;

• George answered the next 6 questions on the next 5 days;

• George answered the next 7 questions on the last 5 days';

Hence, the total questions he answered will be:

5 + 6 + 7 = 18

Therefore, 18 is the total number of questions George answered in 14 days.
