Percentage increase of passed students as compared to previous year: For year 2016–2017, its decreasing so no need to calculate. For year 2014–2015, = (200 – 150)/150 × 100 = 33.33% For year 2015–2016, = (300 – 200)/200 × 100 = 50% For year 2017–2018, = (300 – 250)/250 × 100 = 20% ∴ For the year 2017–2018, the percentage increase in total number of passed students is the lowest in comparison to previous academic year. |
(200 – 150)/150 × 100 = 500/15 = 33.33 (300 – 200)/200 × 100 = 100/2 = 50 (300 – 250)/250 × 100 = 500/25 = 20
