Question

In which of the given year(s) was the production of B type refrigerator closest to its average production over the given years? (Refer to the table below)

| Years |   B  |
|-------|------|
| 2011  | 1800 |
| 2012  | 1890 |
| 2013  | 1910 |
| 2014  | 1940 |
| 2015  | 1960 |

Accepted Answer

Let's calculate the average production of B type refrigerators over the five years:

B (2011): 1800
B (2012): 1890
B (2013): 1910
B (2014): 1940
B (2015): 1960

Sum = 1800 + 1890 + 1910 + 1940 + 1960 = 9500
Average = 9500 / 5 = 1900

Now, let's find the absolute difference of each year's production from the average:

2011: |1800 - 1900| = 100
2012: |1890 - 1900| = 10
2013: |1910 - 1900| = 10
2014: |1940 - 1900| = 40
2015: |1960 - 1900| = 60

The smallest difference is 10, which occurs in both 2012 and 2013.

Therefore, the correct answer is: Both 2012 and 2013.
