Question

There are 250 students in class VII of a school, out of
which 120 students are in Section A, 80 students are
in Section B and rest of the students are in Section C.
Find the percentage of students of class VII that are
in Section C.​

Answer 1

Answer:

20%

Step-by-step explanation:

students in section c=250-(120+80)

=250-200

=50

% of students in class c=50/250×100

=100/5=20%

Answer 2

Given :

→ Total number of students in class VII = 250 students.

→ Students in Section A = 120 students

→ Students in Section B = 80 students

Find :

Percentage of students of class VII that are in Section C.

Solution :

There are 250 students of class VII out of which 120 students are of Section A and 80 students are of Section B.

To find number of students od Section C. We have to add students of Section A and B and then subtract them from total number of students.

i.e.

Students of Section C = Total number of students - (Students of Section A + Students of section B)

$\implies\:250\:-\:(120\:+\:80)$

$\implies\:250\:-\:200$

$\implies\:50$

There are 50 students in Section C of class VII.

According to question, we have to find the percentage if students of class VII that are in Section C.

Perentage = Students in Section C/Total number of students × 100

$\implies\:50/250\:\times\:100$

$\implies \:1/5\:\times\:100$

$\implies \:20\%$

∴ There are 20% students in class VII of Section C.
