Question : Directions: In the following question, the following histogram shows the relationship between the marks obtained by the students and the number of students in an examination. Study the histogram and answer the questions.
The percentage of students who obtained 40 marks or fewer is ____.
Option 1: 25
Option 2: Less than 25, but not 15
Option 3: More than 24
Option 4: 15
Correct Answer: More than 24
Solution :
Based on the given graph in question,
Total number of students = 5 + 10 + 15 + 19 + 13 = 62
Number of students who obtained 40 marks or fewer = 15
$\therefore$ Required percentage = $\frac{\text{Number of students who obtained 40 marks or fewer}}{\text{Total number of students}}× 100=\frac{15}{62}×100 = 24.2\%$
Hence, the correct answer is more than 24.
