Question

Please help! The two way-table shows the number of students in a school who like mathematics and/or physics.

How many more students like physics than mathematics?

A- 10

B- 15

C- 20

D- 25

Answer 1

I think the answer is B.) 15

If you look at the number of students who like mathematics but not physics, that's 5 students.
Then we see that 20 students like physics but not mathematics.
So there's 15 more students

Answer 2

Answer: B- 15

Explanation:

From the given two way-table , then number of students in a school who like mathematics = 20

The number of students in a school who like physics = 35

The number of students in a school who like mathematics and physics = 15

Now, the number of students like only Physics =
`35-15=20`

The number of students like only Mathematics=
`20-15=5`

Thus, the number of students like physics than mathematics will be :-

`20-5=15`
