Study the given table and answer the questions that follows.
The table shows the number of students Appeared (A) and Passed (P) in a examination, from three schools X, Y and Z in five years.
In which year was the difference between the number of students appeared and the
number of students passed the second lowest in school Z?
Solution
for this question, we only have to consider the data from School Z
We need to subtract the number of students who passed from the number of students who appeared for each year and see in which year is that value at the second lowest rank.
2016: 300-285 = 15
2017: 320-304 = 16
2018: 380-362 = 18
2019: 352-325 = 27
2020: 400-381 = 19
If we rank the years in the increasing order of their differences:
2016(15), 2017 (16), 2018 (18), 2020(19), 2019 (27)
We see that the year with the second-lowest difference is 2017
Therefore, Option A is the correct answer.
