Which of the following can be concluded based on the above statements? A There has been an improvement in primary education over the last 5 years B The number of ‘non-smart’ kids has decreased over the last 5 years C The number of kids taking the mandatory school exam has increased over the last 5 years D The number of smart kids has increased as a percentage of the total population of the country Explanation If there are 100 kids taking an exam, the number of students who scored more than 95% of their peers will be 5. If the total number of test-takers increases, then the number of people who scored more than 95% of their peers also increases.

So, the conclusion that can be drawn from the above statements is that the number of kids taking the mandatory school exam has increased over the last 5 years.
