Question 20: Out of 100 students, 75 students like Math and 60 like Literature. If there are 5 students who don’t like both Maths and Literature, how many students like both Literature and Maths?

Let the number of students who like both Literature and Math be x, the number of students who like Math but don’t like Literature is 75 – x.

We have: 75 – x + 60 + 5 = 100

x = 40

So there are 40 students who like both subjects.
