Answer is (A) 2.8% decrease in value
At 2010 Value is 100
2011 90 - since it dropped 10%,
2012 108 - since it increased 20%
2013 97.2 - since it dropped 10%
So from the original 100 - 97.2 = 2.8% decreased.
At 2010 Value is 100
2011 90 - since it dropped 10%,
2012 108 - since it increased 20%
2013 97.2 - since it dropped 10%
So from the original 100 - 97.2 = 2.8% decreased.

In year 2010 Let value be 100, so In 2013 it becomes : 100*0.9*1.2*0.9=97.2
thus change is ((97.2-100)/100)*100=-2.8% hence answer A
thus change is ((97.2-100)/100)*100=-2.8% hence answer A
