The given histogram represents the marks of students in Mathematics test of a certain class.
The total number of students in 350 and the maximum marks of the test are 200.
Study the histogram and answer the question that follows.
The total number of students whose marks are less than 100 is what percentage less than the total number of students whose marks are 120 and above?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 43.2%
Number of students whose marks are less than 100 = 105
Number of students whose marks are more than 120 = 185
Thus, the required percentage = [(185 - 105)/185] × 100
⇒ (80/185) × 100 = 43.24%
