Manisha is a kindergarten class teacher who planned a schedule for the...
The slot is made for 5 days with 4 slots each. Thus the total number of fields to be filled = 5\times4 = 205×4=20
We know each day there is 1 free slot. Let a,ba,b and cc be the number of Compulsory, Optional, and Necessary subjects be there.
Then a+b+c = 6 ....(I)
Then 5+4a+2b+c = 20 or 4a+2b+c = 15....(II) It is clear that c has to be odd.
when c= 1, then b=3 and a = 2
when c= 3, then b=0 and a= 3 which is rejected as we know there is one subject of each category.
Thus Number of Compulsory classes = 2, Number of Optional classes = 3, and Number of Necessary subject = 1.
Let us start by filling in the known information.
> Painting was taught on Wednesday C slot
>Slot D of Monday was a free slot
> Week starts with teaching English

> Physical Education happens only on A slot. Thus we know that it is the subject in the Necessary Category. We know that none of the optional category classes was conducted on Friday. Thus only the Compulsory and Necessary category subject happened on Friday. Thus Physical Education happened on Friday A slot
>On one particular day, Physical Education, Dance, and English were taught in that order. Slot C was a free slot that day. Thus Dance and English are the Compulsory category subjects
Thus Dance is not a subject of Optional Category.

Explanation:

Optional Category Subjects:
- The Optional category subjects happen 2 times a week.
- None of the Optional subjects happened on Friday.
- Exactly one Optional subject was not taught on consecutive days.

Reasoning:
- Painting is taught on Wednesday, which means it is one of the Necessary or Compulsory subjects as it happens only once a week.
- Counting is taught on Monday, which means it is one of the Compulsory subjects as it happens 4 days a week.
- Singing did not happen on Tuesday, leaving it as one of the Optional subjects.
- Dance was not taught on Thursday, so it could potentially be an Optional subject.

Conclusion:
- Based on the given information, Counting is a Compulsory subject, Singing is an Optional subject, and Dance is a subject that could be either Compulsory or Optional.
- Since Dance can be either Compulsory or Optional, it cannot be definitively stated that Dance is not an Optional subject.
- Therefore, the subject that cannot be of the Optional category is Dance (option C).
