Understanding the Teacher Schedule Puzzle

This question is a classic logic puzzle where we need to determine the teaching schedule for six teachers (J, K, L, M, N, O), their respective subjects (Hindi, English, Math, Science, Social Science, Arts), and the day they teach (Monday to Saturday). We are given several clues that link teachers, subjects, and days. Our goal is to build a complete schedule and then identify the subject taught on Friday, which is the day between Thursday and Saturday.

Step-by-Step Deduction Process

Let's break down the clues and fill in the schedule systematically.

Clue 1: J teaches Science on Wednesday.

We can immediately add this to our table.

Clue 2: O teaches Math second day after J.

J teaches on Wednesday. The day after Wednesday is Thursday, and the second day after Wednesday is Friday. So, O teaches Math on Friday.

Clue 3: K teaches on the first day of the week, but teaches neither Hindi nor English.

The first day of the week is Monday. K teaches on Monday. K does not teach Hindi or English. The subjects already assigned are Science (J) and Math (O). So K can teach Social Science or Arts.

Clue 4: L teaches Arts before J.

J teaches on Wednesday. L teaches Arts on a day before Wednesday. The days before Wednesday are Monday and Tuesday. K is already assigned to Monday. So L must teach on Tuesday, and the subject is Arts.

Now we can refine Clue 3. K teaches on Monday and does not teach Hindi or English. We now know L teaches Arts. So K cannot teach Arts. Therefore, K must teach Social Science.

Clue 5: M teaches English before N.

The remaining teachers are M and N. The remaining days are Thursday and Saturday. The remaining subjects are Hindi and English. M teaches English before N, meaning M teaches on an earlier day than N. Thursday is before Saturday. So M teaches on Thursday and N teaches on Saturday. M teaches English, which means N teaches Hindi.

Identifying the Subject Between Thursday and Saturday

The question asks for the subject taught between Thursday and Saturday. The day between Thursday and Saturday is Friday.

Looking at our completed schedule:

• On Thursday, English is taught.
• On Friday, Math is taught.
• On Saturday, Hindi is taught.

The subject taught on Friday, which is between Thursday and Saturday, is Math.

Conclusion

By carefully analyzing each clue and building the schedule step-by-step, we determined that Math is taught on Friday, the day between Thursday and Saturday.

The final arrangement is:

• Monday: K teaches Social Science
• Tuesday: L teaches Arts
• Wednesday: J teaches Science
• Thursday: M teaches English
• Friday: O teaches Math
• Saturday: N teaches Hindi

The subject taught between Thursday and Saturday (i.e., on Friday) is Math.

Additional Information: Types of Logic Puzzles

This type of problem is a classic example of a deductive logic puzzle, often found in reasoning sections of competitive exams. These puzzles require you to use given statements or clues to infer information and build a complete picture or arrangement.

• Grid Puzzles: Like the one solved, where you match items from different categories (teachers, days, subjects).
• Ordering Puzzles: Where you arrange items in a specific sequence based on clues (like the "before N" clue).
• Truth-Teller/Liar Puzzles: Where you deduce who is telling the truth based on their statements.

Solving these puzzles involves careful reading, organizing information (often in tables), and using elimination to deduce unknown facts.
