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 by L?

Solving the Teachers, Subjects, and Days Logical Puzzle
This question is a logical reasoning 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 different days of the week (Monday to Saturday).
Let's break down the given clues and build a table or list to keep track of the assignments.
| Teacher | Subject | Day |
|---|---|---|
| J | ||
| K | ||
| L | ||
| M | ||
| N | ||
| O |
Analyzing the Clues for Teacher, Subject, and Day
Let's go through each clue and fill in the information:
- J teaches Arts on Saturday.
- Teacher: J
- Subject: Arts
- Day: Saturday
- L teaches neither English nor Social Science, but he teaches on Thursday.
- Teacher: L
- Day: Thursday
- Subject ≠ English
- Subject ≠ Social Science
- Wednesday is reserved for Maths taught by K.
- Teacher: K
- Subject: Maths
- Day: Wednesday
- O teaches Science a day before N.
- Teacher: O, Subject: Science, Day: D1
- Teacher: N, Subject: ?, Day: D2
- D1 is the day immediately before D2.
- Social Science is taught a day before Arts.
- Subject: Social Science, Day: Day Before Arts
- Subject: Arts, Day: Day of Arts
Now let's update our table with the direct information from clues 1, 2, and 3:
| Teacher | Subject | Day |
|---|---|---|
| J | Arts | Saturday |
| K | Maths | Wednesday |
| L | Thursday | |
| M | ||
| N | ||
| O |
Deducing More Assignments
Using clue 5, Social Science is taught a day before Arts. We know Arts is on Saturday (taught by J). So, Social Science must be taught on Friday.
- Subject: Social Science
- Day: Friday
Who teaches Social Science on Friday? We have M, N, O remaining to be assigned to Friday, Monday, and Tuesday (the remaining days). The remaining subjects are Hindi, English, Science.
Let's look at clue 4: O teaches Science a day before N. The only consecutive days available are Monday and Tuesday (since Wednesday, Thursday, Friday, and Saturday are already assigned to K, L, M, J respectively based on deductions so far or will be assigned soon). Therefore, O teaches Science on Monday, and N teaches on Tuesday.
- O: Science, Monday
- N: ?, Tuesday
Now we can update the table again:
| Teacher | Subject | Day |
|---|---|---|
| J | Arts | Saturday |
| K | Maths | Wednesday |
| L | Thursday | |
| M | ||
| N | Tuesday | |
| O | Science | Monday |
The remaining day is Friday. The remaining teacher is M. So, M must teach on Friday. We already deduced that Social Science is taught on Friday.
- M: Social Science, Friday
Updated table:
| Teacher | Subject | Day |
|---|---|---|
| J | Arts | Saturday |
| K | Maths | Wednesday |
| L | Thursday | |
| M | Social Science | Friday |
| N | Tuesday | |
| O | Science | Monday |
Now let's consider the remaining teachers (L, N) and remaining subjects (Hindi, English).
- L teaches on Thursday.
- N teaches on Tuesday.
- L does not teach English or Social Science.
We already know M teaches Social Science. The subjects remaining for L and N are Hindi and English.
Since L cannot teach English, L must teach Hindi on Thursday.
Consequently, N must teach the remaining subject, which is English, on Tuesday.
Final Assignments
Let's complete the table with all assignments:
| Teacher | Subject | Day |
|---|---|---|
| J | Arts | Saturday |
| K | Maths | Wednesday |
| L | Hindi | Thursday |
| M | Social Science | Friday |
| N | English | Tuesday |
| O | Science | Monday |
We can verify if all clues are satisfied:
- J teaches Arts on Saturday (Yes).
- L teaches neither English nor Social Science, teaches on Thursday (Yes, teaches Hindi).
- Wednesday is Maths taught by K (Yes).
- O teaches Science a day before N (O teaches Science on Monday, N teaches English on Tuesday. Monday is before Tuesday. Yes).
- Social Science is taught a day before Arts (M teaches Social Science on Friday, J teaches Arts on Saturday. Friday is before Saturday. Yes).
All conditions are met. The question asks which subject is taught by L.
From our final table, L teaches Hindi.
The subject taught by L is Hindi.
Revision Table: Teacher, Subject, and Day Assignments
| Teacher | Subject Taught | Day of Teaching |
|---|---|---|
| J | Arts | Saturday |
| K | Maths | Wednesday |
| L | Hindi | Thursday |
| M | Social Science | Friday |
| N | English | Tuesday |
| O | Science | Monday |
Additional Information on Logical Reasoning Puzzles
Logical reasoning puzzles, like this one involving teachers, subjects, and days, test your ability to deduce information from a set of given clues. These puzzles often require careful organization of information and step-by-step deduction.
Key strategies include:
- Creating a grid or table to map relationships between different categories (like Teacher, Subject, Day).
- Filling in direct information first.
- Using negative clues (like "neither English nor Social Science") to eliminate possibilities.
- Combining clues to make further deductions (like clue 5 leading to the Friday assignment).
- Identifying pairs or sequences described in clues (like "a day before").
- Working through possibilities systematically when direct deductions are not possible.
- Verifying the final solution against all the original clues.
Practicing these types of logical arrangement problems helps improve analytical skills and logical thinking, which are useful for various exams and problem-solving situations.
