Solution
Given
In this question, we are given that
- • A graph shows the number of towels imported to Japan from China, and the total number of towels imported to Japan from all countries, including China
• The average (arithmetic mean) number of towels imported from China per month was the same for the last 3 months of 2000 as it was for the first 9 months of 2000
To find
We need to determine
- • In 2000, approximately how many million dozen towels were imported from China during the 12 months of 2000?
Approach and Working out
In 2000, the number of towels imported from China in the first 9 months = 43 millions of dozens
- • Hence, the average number of towels imported from China in 2000 in a month = 43/9 million dozen
As the average for the first 9 months is same as the average for the last 3 months, we can say that per month average is the same for all the months in 2000
Therefore, the average number of towels imported from China in 2000 in any month = 43/9 million dozen
- • Hence, total number of towels imported from China in 2000 = 43/9 x 12 = 57.3 (approx)
Thus, option A is the correct answer.
Correct Answer: Option A
