J, K L, M, N and O are six teachers. Each one teaches a different subject out of Hindi, English, Math, Science, Social Science and Arts, NOT necessarily in the same order. Each of them teaches on only one day, from Monday to Saturday. NOT necessarily in the same order. J teaches Arts on Saturday. L teaches neither English nor Social Science, but he teaches on Thursday. Wednesday is reserved for Maths taught by K. O teaches Science a day before N. Social Science is taught a day before Arts. Who teaches Social Science?

Solving the Teacher Schedule Logic Puzzle
This logic puzzle involves six teachers (J, K, L, M, N, O), six different subjects (Hindi, English, Math, Science, Social Science, Arts), and six days of the week (Monday to Saturday). Each teacher teaches one subject on one specific day. We need to use the given clues to determine the schedule and identify who teaches Social Science.
Step-by-Step Deduction Process
Let's break down the clues and build a schedule.
- Clue 1: J teaches Arts on Saturday.
This gives us a direct assignment: Teacher J is assigned to Saturday and teaches Arts.
- Clue 3: Wednesday is reserved for Maths taught by K.
This provides another fixed point: Teacher K teaches Maths on Wednesday.
- Clue 2: L teaches neither English nor Social Science, but he teaches on Thursday.
We know L teaches on Thursday. We also know L's subject is not English and not Social Science.
- Clue 5: Social Science is taught a day before Arts.
Arts is taught on Saturday (from Clue 1). A day before Saturday is Friday. Therefore, Social Science is taught on Friday.
Let's summarize the information gathered so far in a table:
| Day | Teacher | Subject |
|---|---|---|
| Monday | ? | ? |
| Tuesday | ? | ? |
| Wednesday | K | Maths |
| Thursday | L | Not English, Not Social Science |
| Friday | ? | Social Science |
| Saturday | J | Arts |
Now, let's use the remaining clues and fill in the gaps.
- We have days Monday, Tuesday, Friday left to assign teachers and subjects. The remaining teachers are M, N, O. The remaining subjects are Hindi, English, Science, Social Science. We already know Social Science is on Friday.
- Clue 4: O teaches Science a day before N.
This means O and N teach on consecutive days. Looking at the available days (Monday, Tuesday, Friday), the only consecutive days are Monday and Tuesday. So, O teaches on Monday and N teaches on Tuesday. O teaches Science, so Science is taught on Monday.
Updated information:
| Day | Teacher | Subject |
|---|---|---|
| Monday | O | Science |
| Tuesday | N | ? |
| Wednesday | K | Maths |
| Thursday | L | Not English, Not Social Science |
| Friday | ? | Social Science |
| Saturday | J | Arts |
- The teacher left is M. The day left to assign a teacher is Friday. Therefore, M teaches on Friday.
- We now know M teaches Social Science on Friday.
Let's complete the table with the remaining subjects. The subjects left are Hindi and English. The teachers left to assign subjects to are N (Tuesday) and L (Thursday).
- From Clue 2, L does not teach English (or Social Science, which is already assigned). Since only Hindi and English are left, and L doesn't teach English, L must teach Hindi on Thursday.
- This leaves English for N to teach on Tuesday.
Final Schedule
Putting all the pieces together, the final schedule is:
| Day | Teacher | Subject |
|---|---|---|
| Monday | O | Science |
| Tuesday | N | English |
| Wednesday | K | Maths |
| Thursday | L | Hindi |
| Friday | M | Social Science |
| Saturday | J | Arts |
Answering the Question: Who teaches Social Science?
Based on our complete deduction, the teacher assigned to Friday, who teaches Social Science, is M.

| Teacher | Day | Subject |
|---|---|---|
| J | Saturday | Arts |
| K | Wednesday | Maths |
| L | Thursday | Hindi |
| M | Friday | Social Science |

| O | Monday | Science |
Additional Information: Logic Puzzle Strategies
Logic puzzles like this require careful reading and systematic deduction. Here are some helpful strategies:
- Read all the clues carefully before starting.
- Use a table or grid to organize the information. This helps visualize relationships between different elements (teachers, days, subjects).
- Start with the most direct clues that give fixed assignments (like J teaching Arts on Saturday or K teaching Maths on Wednesday).
- Use negative clues (like L not teaching English or Social Science) to eliminate possibilities.
- Look for clues that link elements together, such as consecutive days ("a day before").
- Systematically fill in the table as you make deductions.
- Once you believe you have the solution, quickly review the original clues to ensure your solution doesn't contradict any of them.
