Directions: The following bar graph shows the sales (in thousands) of magazines from six branches (A, B, C, D, and F) of a publishing company during two consecutive years 2021 and 2022.
the average sales of branches A, C, and F in 2021 is what percent of the average sales of branches A, B, and C in 2022?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 87.5%.
From the given bar graph,
The Total sales of branches A, B, and C in 2022 = 105 + 65 + 110 = 280
The total sales of branches A, C, and F in 2021 = 80 + 95 + 70 = 245
Average = Sum of observations/Number of observations
The average sales of the branches A, B, and C in 2022 = 280/3 = 93.33
The average sales of the branches A, C, and F in 2021 = 245/3 = 81.67
Hence, The required percentage = (81.67/93.33) × 100 = 87.5%
