Question

Which year showed the best result in MBA entrance exams (in terms of percentage of students who cleared?)

A. 2000
B. 2001
C. 2002
D. cannot be determined

Answer 1

Hint: Find the number of students who appeared in the test and the number of students who cleared the exam in each year. Then, find the percentage of students who cleared the MBA exam each year. The year when the percentage is maximum is the required answer.

Complete step-by-step answer:
We will calculate the percentage of students who cleared MBA in each year.
From the graph, we can see that the total students who appeared in the exam are 170 and only 140 cleared out of the total students.
Therefore, the percentage can be calculated as $\dfrac{{140}}{{170}} \times 100 = 82.35\% $
This implies that 82.35% students cleared the MBA exam.
In the year 2001, the number of students that appeared in the exam are 180 and the students who cleared the MBA entrance are 150.
Therefore, the percentage of students who cleared MBA exam in 2001 is
$\Rightarrow$$ \dfrac{{150}}{{180}} \times 100 = 83.33\% $
Similarly, we will find the percentage of students who cleared the MBA exam in 2002.
From the graph, total students who participated in 2002 are 200 and 160 students cleared the MBA exam.
Then, the required percentage is $\dfrac{{160}}{{200}} \times 100 = 80\% $
Therefore, the maximum percentage is in 2001.
Hence, option B is correct.

Note: The given graph is a bar graph. The graph has to be read carefully to find the required values. Also, the percentage is calculated as $\dfrac{{{\text{number of students who cleared MBA exam}}}}{{{\text{total number of students who appeared exam}}}} \times 100$.
