Total number of tabs sold from 2011 to 2016 = 30 + 25 + 37 + 40 + 30 + 20 = 182
Total number of mobile phones sold from 2011 to 2016 = 35 + 33 + 33 + 35 + 36 + 40 = 212
Therefore, ratio = 182/212 = 91:106

For mobile the sale in 2011 was 35 and in 2012 was 33. Therefore, the sale decreased. In 2012 was 33 and 2013 was also 33. Therefore, there was no change in the sale. In 2013 was 33 and 2014 was 35. Therefore, there was an increase by 2 thousand. Percent increase = 2/33 * 100 = 6.06%. In 2014 was 35 and 2015 was 36. So, there was increase of 1 thousand. Percent increase = 1/35 * 100 = 2.85%. In 2015 was 36 and 2016 was 40. Therefore, there was an increase of 4 thousand. Percent increase = 4/36 * 100 = 11.11%.

Thus, highest increase in the sale was in year 2016.

For tabs the sale in 2011 was 30 and in 2012 was 25. Therefore, the sale decreased. In 2012 was 25 and 2013 was also 37. Therefore, there was increase by 12 thousand. Percent increase = 12/25 * 100 = 14%. In 2013 was 37 and 2014 was 40. Therefore, there was an increase by 3 thousand. Percent increase = 3/37 * 100 = 8.10%. In 2014 was 40 and 2015 was 30.

In 2014: 35 + 40 = 75

In 2015: 36 + 30 = 66

In 2016: 40 + 20 = 60

Therefore, the decrease occurs during 2012, 2015, and 2016. So the percent decrease in 2012 = 7/65 * 100 = 10.76%

In 2015 the percent decrease: 9/75 * 100 = 12%

In 2006 = 75000

Company S’s sale in 2005 = 95000

In 2006 = 105000

Total sale of Company Q = 85000 + 75000 = 160000

Total sale of Company S = 95000 + 105000 = 200000

Therefore, ratio = 160000/200000 = 4/5 = 4:5

Average of all the six companies in 2005 = 90 + 85 + 105 + 95 + 85 + 80/ 6

= 540/6 = 90
