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?

Understanding the Logic Puzzle: Teachers, Subjects, and Days
This question is a logic puzzle where we need to match six teachers (J, K, L, M, N, O) with 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 are given several clues that help us deduce the complete schedule. Let's break down the clues and build the schedule step-by-step.
Step-by-Step Deduction of the Schedule
We can use a table to keep track of the information we deduce. We have days, teachers, and subjects to assign.
| Day | Teacher | Subject |
|---|---|---|
| Monday | ? | ? |
| Tuesday | ? | ? |
| Wednesday | ? | ? |
| Thursday | ? | ? |
| Friday | ? | ? |
| Saturday | ? | ? |
Let's incorporate the given clues:
- J teaches Arts on Saturday.
Day Teacher Subject Monday ? ? Tuesday ? ? Wednesday ? ? Thursday ? ? Friday ? ? Saturday J Arts - Wednesday is reserved for Maths taught by K.
Day Teacher Subject Monday ? ? Tuesday ? ? Wednesday K Math Thursday ? ? Friday ? ? Saturday J Arts - L teaches neither English nor Social Science, but he teaches on Thursday.
We know L teaches on Thursday. We don't know the subject yet, but we know it's not English or Social Science.
Day Teacher Subject Monday ? ? Tuesday ? ? Wednesday K Math Thursday L ?(Not English/Social Science) Friday ? ? Saturday J Arts - Social Science is taught a day before Arts.
Since Arts is on Saturday, Social Science must be on the day before Saturday, which is Friday.
Day Teacher Subject Monday ? ? Tuesday ? ? Wednesday K Math Thursday L ?(Not English/Social Science) Friday ? Social Science Saturday J Arts - O teaches Science a day before N.
This means if O teaches Science on day X, N teaches on day X+1. Let's look at the remaining days: Monday, Tuesday, Friday. The only available consecutive days where this can happen are Monday (Day X) and Tuesday (Day X+1). Friday is Day X for Saturday, but Saturday is J, not N. Wednesday and Thursday are already taken.
So, O teaches Science on Monday, and N teaches on Tuesday.
Day Teacher Subject Monday O Science Tuesday N ? Wednesday K Math Thursday L ?(Not English/Social Science) Friday ? Social Science Saturday J Arts
Now let's complete the table with the remaining teachers and subjects:
- Teachers remaining: M. The only day left without a teacher is Friday. So, M teaches on Friday.
- Subjects remaining: Hindi, English.
- Days remaining with unknown subjects: Tuesday (N), Thursday (L).
| Day | Teacher | Subject |
|---|---|---|
| Monday | O | Science |
| Tuesday | N | ? |
| Wednesday | K | Math |
| Thursday | L | ?(Not English/Social Science) |
| Friday | M | Social Science |
| Saturday | J | Arts |
We know L teaches on Thursday and does not teach English or Social Science. Social Science is already assigned to M. So, L cannot teach Social Science. Since L cannot teach English either, L must teach the other remaining subject, which is Hindi.
If L teaches Hindi on Thursday, the only remaining subject for N on Tuesday is English.
Final Schedule
Based on all the clues, the final schedule is:
| Day | Teacher | Subject |
|---|---|---|
| Monday | O | Science |
| Tuesday | N | English |
| Wednesday | K | Math |
| Thursday | L | Hindi |
| Friday | M | Social Science |
| Saturday | J | Arts |
Answering the Question
The question asks: "Which subject is taught on the day between Science and Math?"
- Science is taught on Monday.
- Math is taught on Wednesday.
- The day between Monday and Wednesday is Tuesday.
Looking at our final schedule, the subject taught on Tuesday is English.
Therefore, English is the subject taught on the day between Science and Math.
Revision Table: Checking the Schedule
| Clue | Is the schedule consistent? | Explanation |
|---|---|---|
| J teaches Arts on Saturday | Yes | Saturday: J, Arts |
| L teaches neither English nor Social Science, teaches on Thursday | Yes | Thursday: L, Hindi (Neither English nor Social Science) |
| Wednesday is reserved for Maths taught by K | Yes | Wednesday: K, Math |
| O teaches Science a day before N | Yes | Monday: O, Science. Tuesday (the next day): N, English. (O teaches Science on Mon, N teaches on Tue) |
| Social Science is taught a day before Arts | Yes | Friday: Social Science. Saturday (the next day): Arts. |
Additional Information: Logic Puzzle Strategies
Logic puzzles like this require careful reading and systematic deduction. Here are some tips:
- Read all clues carefully before starting.
- Use a grid or table to organize information and eliminate possibilities.
- Start with the most direct clues that give definite assignments (like J on Saturday, K on Wednesday).
- Combine clues to make further deductions (like Social Science being the day before Arts).
- Use elimination based on negative clues (L not teaching English or Social Science).
- Review your completed grid or table against all original clues to ensure consistency.
These puzzles test your ability to process multiple pieces of information and connect them logically to arrive at a solution.
