Can someone explain how 2nd answer is 2011?
­Hi, you can find greatest changes at two places:
2010 to 2011.... In 2011 it becomes around 1775 from 1400, so change is (1775-1400)/1400 = 26.78%
2014 to 2015.... In 2015 it comes down to 1675 from 2190, so change is (2190-1675)/2190 = 23.51%

Thus answer is 2011.

Maximum change is in 2015 but maximum % change is in 2011.

Hope it helps

What is the answer to this q?
­Hi,
I. The import and export data presented in the chart above indicates that the range of  import/export/trade surplus(export-import) was the minimum through the period 2010 to 2017.
Import Range = 2190-1400 = 790
Export Range = 2350-1590 = 760
Trade surplus range: It will be given by the gap between the two lines as export is more than imports every year.
We can see that the trade surplus is maximum in 2015 = 2250-1680 = 570, and minimum in 2011 = around 150.
Thus range = 570-150 = 420
Answer : Range of Trade surplus.

II. The year 2 saw the maximum % change in the imports.
2010 to 2011.... In 2011 it becomes around 1775 from 1400, so change is (1775-1400)/1400 = 26.78%
2014 to 2015.... In 2015 it comes down to 1675 from 2190, so change is (2190-1675)/2190 = 23.51%

Thus answer is 2011.

Maximum change is in 2015 but maximum % change is in 2011.

­I. The import and export data presented in the chart above indicates that the range of  [Trade surplus] was the minimum through the period 2010 to 2017.

The range of
  • Import: 400 = 1800 - 1400
  • Export: 650 = 2250 - 1600
  • Trade surplus: 300 = 400 (year 2017) - 100 (year 2014)
=> Trade surplus

II. The year [2011] saw the maximum % change in the imports.

Maximum change should be an increase => can be >100% (%change in decrease cannot be higher than 100%)
=> From 2020 to 2011 has steepest slope 
=> 2011 saw the greatest increase

Can someone explain how 2nd answer is 2011?
­For Q2- It asked for the year which has a maximum % Change in Imports than the previous. Let us assume 100 Billions = 1 point = 1P, so 1800 Billioin= 18P

1. 2010, we can ignore this cause we dont have 2009 Data.
2. 2011, in 2010 ~14P and 2011 ~18P i.e, 18/14 we have~28% Growth
3. 2012, in 2011 ~18P and 2012 ~18P Growth= 18/18~very least growth
4. 2013, in 2012 ~18P and 2013 ~20P Growth= 20/18~11% Growth
5. 2014, in 2013 ~20P and 2014 ~22P Growth= 22/20~10% Growth
6. 2015, in 2014 ~22P and 2015 ~17P Growth= 22/17~23% Loss
7. 2016, in 2015 ~17P and 2016 ~16P Growth= 17/16~06% Loss
8. 2017, in 2016 ~16P and 2017 ~18P Growth= 18/16~12% Growth

After checking all the events, we can say in the year 2011 we have major change, i.e, 28% Growth, Ofcourse these values are not accurate but closly represent to the data, this helps to resolve easily.

Please correct me if I miss anything.
Thank you :)
