Study the histogram and answer the question given below.
The graph represents the number of students obtaining a percentage of marks in class X Board examination in 2018 in a school.
The number of students who have secured less than 60% marks is what per cent less than the number of students who have secured 80% marks and above?
Answer & explanation
Correct answer: option 2
Number of students with less than 60% marks = 10 + 30 = 40
Number of students with 80% marks and above = 40 + 25 = 65
Required percentage = \(\frac{65 - 40}{65}\) × 100
= \(\frac{25}{65}\) × 100
= 38.5%
