Question

The students must take part in at least one of the activities among the extra curricular activities in a school. Out of 40 students of a class, 25 students take part in debate and 30 students take part in quiz contest, then i. show the above information in a Venn diagram. ii. how many students have taken part in both activities? iii. how many students have taken part in only one activity?​

Answer 1

• Total number of students = 40
• Debate = 25 students
• Quiz contest = 30 students

i)

Sum of two parts:

• 25 + 30 = 55

Students taking part in both parts:

• 55 - 40 = 15

ii)

Debate only:

• 25 - 15 = 10

Quiz contest only:

• 30 - 15 = 15

Venn diagram will look like this:

• 10 15 15
• Debate - both - quiz contest
