Question

The bar graph shows the number of students in different classes.

i) Which class has the maximum number of students?

ii) Which class has the least number of students?

iii) Arrange the classes in the ascending order of their number of students.

iv) Find the total number of students from classes$I$ to $VI$

v) Find the ratio of the number of students in the class$II$ to class$VI$

Answer 1

i) According to the given information, the class$VI$ has $45$ students which are maximum as compared to other

$\therefore$ the class $VI$ with the maximum number of students

ii) According to the given information, the class $III$ has$15$ students which are minimum as compared to other

$\therefore$ the class $III$ has the least number of students

iii) According to the given information, The classes are in the ascending order of their number of students:$III,IV,I,II,V,VI.$

iv) The total number of students from classes $I$ to $VI$ $=Class(I+II+III+IV+V+VI)$

$=25+30+15+20+35+45$

$=170students.$

$\therefore$ The total number of students from classes $I$ to $VI=170students$

v) Ratio = $\frac{NumberofstudentsinclassII}{NumberofstudentsinclassVI}$

= $\frac{30}{45}$

Ratio = $\frac{2}{3}$

$\therefore$the ratio of the number of students in the class$II$ to class$VI=2:3$
