Study the bar graph and answer the question.

The total number of trees planted in state B in 2015 and 2017 was what percentage less than the total number of trees planted in state A in 2014, 2016 and 2017? (Your answer should be correct to one decimalplace.)

20.8

Total number of trees planted in B in  2015 & 2018 = 118 + 100 + 72 = 290

Total number of trees planted in A in 2014 , 2016 & 2017 = 70 + 78 + 92 = 240

Required percentage = \(\frac{290 - 240}{240}\) × 100

= \(\frac{50}{240}\) × 100

= 20.8%
