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.

Pitfall for the above shortcut : say you have 10,20 in year 2000 and 20,50 in year 2001, even though pure bar changes are 4, less than the above 6, but the % increase would be whopping 133%.

Lesson: always make sure you check at the starting years, where the smaller differences can have larger %change.

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.
