Question

in a school ,there are 150 students .out of these 80 students enrolled for mathematics class, 50 enrolled for English class, and 60 enrolled for physics class . The students enrolled for English cannot attend any other class , but the students of mathematics and physics can take two course at times. find the number of students who have taken both physics and mathematics.

Answer 1

Answer:

40

Step-by-step explanation:

First we need to subtract the 50 students enrolled in English class.

150 - 50 = 100

Next, let's add the mathematics students and the physics students.

80 + 60 = 140

Then we subtract the total amount of mathematics and physics students by the total number of students.

140 - 100 = 40

Therefore, there are 40 students who take both mathematics and physics.
