The given Bar Graph presents the results in terms of the number of students in a school for the five academic years, 2013-2014 to 2017-2018.
In which year the percentage increase in total number of students is the lowest in comparison to its previous academic year?
total number of students in 2013-2014=150+100=250
total number of students in 2014-2015=200+100=300
total number of students in 2015-2016=300+50=350
total number of students in 2016-2017=250+100=350
total number of students in 2017-2018=300+100=400
percentage increase in total number of students in 2014-2015=Â $$\frac{300-250}{250}$$*100=$$\frac{50}{250}$$*100=20%
percentage increase in total number of students in 2015-2016=$$\frac{350-300}{300}$$*100=Â $$\frac{50}{300}$$*100=16.66%
percentage increase in total number of students in 2016-2017=$$\frac{350-350}{350}$$*100=Â $$\frac{0}{350}$$*100=0%
percentage increase in total number of students in 2017-2018=$$\frac{50}{350}$$*100=Â $$\frac{50}{350}$$*100=14.28%
from above calculation, percentage increase in total number of students in 2016-2017 is lowest.
