Study the given histogram and answer the question that follows.
The histogram represents the percentage of marks scored by a number of students in the class X Board Examination in 2018 in a school.
Total number of students = 250
The number of students who have secured less than 60% of marks is approximately what percentage more than the number of students who have secured 90% marks and above?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60%.
Number of students who have secured less than 60% of marks = 10 + 30 = 40
Number of students who have secured 90% marks and above = 25
Percentage = [40 - 25]/25 × 100 = 60%
