Question

A math class had 27 students in it. Of those, 14 are also enrolled in History 17 are enrolled in English. What is the minimum % of the students in class who are also enrolled in History and English?

​

Answer 1

14.81%

Explanation:

Known :

• A math class has 27 students
• 14 of them enrolled in History
• 17 of them enrolled in English

Asked :

• The minimum % of students in the class who are also enrolled in History and English

Solution :

Let's consider there are zero students who enrolled nothing (because the question asked the minimum) and x = the amount of students who enrolled both History and English.

x = (14 + 17) - 27

x = 31 - 27

x = 4

Now, we can easily calculate the number of students who enrolled in both History and English by percentage. Let's consider that y = the number of students who enrolled in both History and English by percentage.

y = 4/27

y = 14.81%

Conclusion :

The number of students who enrolled in both History and English by percentage is 14.81%
