There are six teachers A, B, C, D, E and F in a school. Each of the teachers teaches two subjects, one compulsory subject and the other optional subject. D's optional subject is History while three others have it as compulsory subject. E and F have Physics as one of their subjects. F's compulsory subject is Mathematics which is an optional subject of both C and E. History and English are A's subjects but in terms of compulsory and optional subjects, they are reverse of those of D's. Chemistry is an optional subject of any one of them. There is only one female teacher in the school who has English as her compulsory subject.
What is C's compulsory subject?
- History
- Physics
- Chemistry
- English
The Correct Option is A
Solution and Explanation
The correct option is (A): History
Explanation: To determine C's compulsory subject, let's analyze the given information step by step:
1. Teachers and Subjects:
- D's Subjects: History (optional), English (compulsory).
- E and F: Both have Physics as one of their subjects.
- F's Subjects: Mathematics (compulsory), which is optional for C and E.
- A's Subjects: History and English, but in reverse of D's; therefore, A's compulsory subject is English and optional is History.
- Chemistry: Is an optional subject for one of them, but we need to find who it is.
2. Female Teacher: There is only one female teacher with English as her compulsory subject. Since A has English as a compulsory subject, A must be the female teacher.
3. Finding C's Compulsory Subject:
- Since D's optional subject is History and A's compulsory subject is English, C must have Physics as the compulsory subject (as D and A's subjects are reversed).
- Therefore, C's compulsory subject cannot be History or English, so it must be the remaining subject.
Given these deductions, we conclude:
- C's compulsory subject must be History.
