Answer is $2006$

No need to do any calculations ,just observe the bar chart.

Here $\%$ increase is asked, so just check for previous year & next year pair, where you can find maximum positive change.

Consider year $2006$.

Red Bar is above $3$ steps than $2005$ AND Blue Bar is $3$ steps more than $2005$, total $ = 3 + 3 = 6$, it's maximum.

  Exports + Imports Increase % Increase = (Increase/Old_Value) * 100
2000 90 - -
2001 110 20 22.22
2002 130 20 18.18
2003 130 0 0
2004 150 20 15.38
2005 160 10 6.66
2006 220 60 37.5
2007 230 10 4.54

So, 2006.

Using Bar chart , calculating % increase in combined  import and export is highest in 2006.

in 2005 combined import and export is 160  (70+90)

in 2006 combined import and export is  220  (100+120)

so %increase is  [(220-160)/160]*100= (60/160)*100

=37.5%

Which is Highest increment in any other given year in bar graph.
