Question

The students of Grade 7 are categorized based on the marks obtained in Physics. The following histogram depicts the data:

Which marks interval has the $2^{nd}$ highest number of students?

• A. $0-40$ marks
• B. $40-60$ marks
• C. $60-80$ marks
• D. $80-100$ marks

Answer 1

The correct option is B $40-60$ marks

The grouped frequency table of the given data is as follows:
Marks Interval Number of Students

$0\le \text{Marks}<40$	$5$
$40\le \text{Marks}<60$	$20$
$60\le \text{Marks}<80$	$50$
$80\le \text{Marks}<100$	$10$

The highest number of students, i.e., $50$ lies in the interval of $60-80$ marks.
The $2^{nd}$ highest number of students, i.e., $20$ lies in the interval of $40-60$ marks.

Hence, the correct option is (b).
