Question : Directions: The Histogram shows the marks of 50 students in an examination. Examine the diagram and answer the questions [Marks are given in the integers only].
What percent of students did obtain marks above 60?
Option 1: 60%
Option 2: 80%
Option 3: 70%
Option 4: 75%
Correct Answer: 70%
Solution :
Based on the given graph in the question,
Number of students obtaining above 60 marks = 10 + 12 + 5 + 8 = 35
Total number of students = 1 + 4 + 2 + 8 + 10 + 12 + 5 + 8 = 50
$\therefore$ Required percentage = $\frac{\text{Number of students obtaining above 60 marks}}{\text{Total number of students}}× 100=\frac{35}{50}× 100 = 70\%$
Hence, the correct answer is 70%.
