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 passed students is the lowest in comparison to its previous academic year?

Option 4 : 2017–2018

For year 2014–2015, percentage increase of passed students as compared to previous year = (200 – 150)/150 × 100 = 33.33%

For year 2015–2016, percentage increase of passed students as compared to previous year = (300 – 200)/200 × 100 = 50%

For year 2016-2017 percentage increase of passed students as compared to previous year = (250-300)/300 × 100 = -16.66%

(Negative sign means there is decrease in percentage of passed students in 2016-2017 in comparison to 2015 -2016)

For year 2017–2018, percentage increase of passed students as compared to previous year = (300 – 250)/250 × 100 = 20%
