Question

50 students studying both Maths and English. 90 students study either maths or english. If 25 students study eng not maths. How many students study Maths but not english?​

Answer 1

The answer would be 15

Answer 2

15 students study math and not English

Explanation:

lets take the # or people who study math but not English as "x"

so 90 students study math or English

25 students study English and not math

and

50 study both

since 90 students study math or English that is what our equation will equal.

so

25+x+50=90

25+50=75

75+x=90

subtract "75" from both sides:

x=15

Hope this helps!
