Deduce Teachers' Schedule
We need to determine the subject taught on Thursday using the given clues about six teachers (J, K, L, M, N, O), their subjects, and the days they teach (Monday to Saturday).
Step-by-Step Schedule Construction
-
Clue 1: J teaches Science on Wednesday.
- Wed: J (Science)
-
Clue 2: K teaches on Monday. K does not teach Hindi or English.
- Mon: K (Not Hindi, Not English)
-
Clue 3: O teaches Math second after J. Since J teaches on Wednesday, the second day after Wednesday is Friday.
- Fri: O (Math)
-
Clue 4: L teaches Arts before J. J teaches on Wednesday, so L must teach on Monday or Tuesday. Monday is taken by K. Therefore, L teaches Arts on Tuesday.
- Tue: L (Arts)
-
Clue 5: Determine K's subject. Subjects remaining for K on Monday are Hindi, English, Math, Science, Social Science, Arts. We know K is not Hindi or English. J teaches Science, O teaches Math, and L teaches Arts. The only remaining subject K can teach is Social Science.
- Mon: K (Social Science)
-
Clue 6: M teaches English before N. The remaining days are Thursday and Saturday. The remaining subjects are Hindi and English. To satisfy "M teaches English before N", M must teach English on Thursday, and N must teach Hindi on Saturday.
- Thu: M (English)
- Sat: N (Hindi)
Final Schedule
| Day | Teacher | Subject |
| Monday | K | Social Science |
| Tuesday | L | Arts |
| Wednesday | J | Science |
| Thursday | M | English |
| Friday | O | Math |
| Saturday | N | Hindi |
Answer Derivation
According to the constructed schedule, the subject taught on Thursday is English.
