There are 40 students, 30 of them passed in English, 25 of them passed...
Solution:

Given,
Total number of students = 40
Number of students passed in English = 30
Number of students passed in Maths = 25
Number of students passed in both English and Maths = 15

To find: Number of students passed in English only but not in Maths

Let's use the formula of Inclusion-Exclusion Principle to find the number of students who passed in English only but not in Maths.

n(A U B) = n(A) + n(B) - n(A ∩ B)

where,
n(A U B) = Number of students passed in either English or Maths or both
n(A) = Number of students passed in English
n(B) = Number of students passed in Maths
n(A ∩ B) = Number of students passed in both English and Maths

Substituting the given values in the above formula, we get

n(English U Maths) = 30 + 25 - 15
n(English U Maths) = 40

Therefore, the number of students who passed in either English or Maths or both is 40.

Now, we can find the number of students who passed in English only by subtracting the number of students who passed in both English and Maths from the number of students who passed in English.

n(English only) = n(English) - n(English ∩ Maths)
n(English only) = 30 - 15
n(English only) = 15

Therefore, the number of students who passed in English only but not in Maths is 15.

Hence, the correct option is A) 15.
