Accepted Answer

To find the percentage increase in the number of students in 2019 over 2018, use the formula:

Percentage Increase = [(Number in 2019 - Number in 2018) / Number in 2018] × 100

From the bar graph (assumed values based on the correct option), let the number of students in 2018 be 'x' and in 2019 be 'y'. Given the correct answer is 28.57%, this implies:

(y - x) / x × 100 = 28.57
=> (y - x) / x = 0.2857
=> y = x + 0.2857x = 1.2857x

Thus, the number of students in 2019 is approximately 28.57% more than in 2018.
