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.
N
Let's solve this logic puzzle about six teachers, their subjects, and the days they teach from Monday to Saturday. We have six teachers: J, K, L, M, N, and O. They teach six different subjects: Hindi, English, Math, Science, Social Science, and Arts. Each teacher teaches one subject on one specific day from Monday to Saturday.
Analyzing the Teacher and Day Puzzle Clues
We are given the following clues to determine who teaches which subject on which day:
- J teaches Science on Wednesday.
- O teaches Math second after J.
- K teaches on the first day of the week (Monday), but teaches neither Hindi nor English.
- M teaches English before N.
- L teaches Arts before J.
Step-by-Step Deduction to Solve the Teacher Schedule
Let's use these clues to fill in the schedule for each teacher, day, and subject.
- Clue 1: J teaches Science on Wednesday. We can fill this in directly.
- Clue 2: O teaches Math second after J. J teaches on Wednesday. The days after Wednesday are Thursday, then Friday. So, second after Wednesday is Friday. O teaches Math on Friday.
- Clue 3: K teaches on the first day of the week. The first day is Monday. So, K teaches on Monday. K does not teach Hindi or English.
- Clue 5: L teaches Arts before J. J teaches on Wednesday. L must teach Arts on a day before Wednesday. The available days before Wednesday are Monday and Tuesday. We already know K teaches on Monday. So, L must teach Arts on Tuesday.
Let's summarize what we know so far in a table:
| Day | Teacher | Subject |
|---|---|---|
| Monday | K | Not Hindi, English |
| Tuesday | L | Arts |
| Wednesday | J | Science |
| Thursday | ? | ? |
| Friday | O | Math |
| Saturday | ? | ? |
Now let's use the remaining information and clues:
- Deduction from Clue 3 and Clue 5: K teaches on Monday and does not teach Hindi or English. We know Arts is taught by L on Tuesday. The subjects taught so far are Arts, Science, and Math. The remaining subjects are Hindi, English, and Social Science. Since K does not teach Hindi or English, K must teach Social Science on Monday.
Updated table:
| Day | Teacher | Subject |
|---|---|---|
| Monday | K | Social Science |
| Tuesday | L | Arts |
| Wednesday | J | Science |
| Thursday | ? | ? |
| Friday | O | Math |
| Saturday | ? | ? |
- Using Clue 4 and remaining slots: M teaches English before N. The remaining days are Thursday and Saturday. The remaining teachers are M and N. The remaining subjects are Hindi and English. Since M teaches English before N, M must teach on Thursday and N on Saturday. M teaches English. This means N must teach the last remaining subject, which is Hindi, on Saturday.
The complete schedule is:
| Day | Teacher | Subject |
|---|---|---|
| Monday | K | Social Science |
| Tuesday | L | Arts |
| Wednesday | J | Science |
| Thursday | M | English |
| Friday | O | Math |
| Saturday | N | Hindi |
Identifying the Teacher on Saturday
Based on the complete schedule derived from the clues, the teacher who teaches on Saturday is N.

Additional Information on Logic Puzzles
Logic puzzles like this one require careful reading and systematic deduction. It's often helpful to use tables or grids to keep track of the information and eliminate possibilities as you process each clue. Key strategies include:
- Identifying fixed points first (like J on Wednesday with Science).
- Using relative position clues (like "second after" or "before") to link known points to unknown ones.
- Eliminating options based on negative clues (like K not teaching Hindi or English).
- Keeping track of which items (teachers, days, subjects) are already assigned.
- Combining clues to make further deductions and fill in the remaining gaps.
Practice with different types of logic puzzles helps improve analytical and problem-solving skills.
Important Questions from Scheduling

Which subject is taught between Thursday and Saturday?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. Which subject is taught on the day between Science and Math?
There is only one runway which will be used by seven flights one by one. P and Q will use the runway neither first nor last. S will use it second after R. M will use it second before O. N will use it after O and before R. Q will use it just before S. Who will use the runway in the middle?
