Answer 1

The Correct Option is D

We are given the following facts:
1. There are five persons — A, B, C, D, and E. Each has one unique profession: Singer, Dancer, Painter, Teacher, and Doctor.
2. Three of them — A, C, and Doctor — prefer rice to chapatti, while B and the Painter prefer chapatti to rice.
3. The Teacher, D, and A are friends, but two of them prefer chapatti to rice.
4. The Singer is C's brother.
Step 1: Assign rice/chapatti preferences.
From statement (2): A and C prefer rice; B and Painter prefer chapatti. The Doctor also prefers rice. This means the Painter is not A, C, or Doctor.
Step 2: Identify the Painter.
Since Painter prefers chapatti and B also prefers chapatti, B could be the Painter.
Step 3: Use friendship clue.
From statement (3): Teacher, D, and A are friends; two of them prefer chapatti. This means that among Teacher, D, and A, only one prefers rice. But we know A prefers rice, so Teacher and D must prefer chapatti.
Step 4: Link Singer to C.
From statement (4): Singer is C's brother. Since the professions are unique, Singer cannot be C. Given the assignments, only A fits the role of Singer after eliminating other professions from the clues.
Therefore, \(\boxed{\text{A is the Singer}}\).

Answer 2

Continuing from the deductions in Q1:
Step 1: Remaining professions.
We already know A is the Singer and B is the Painter. C’s profession is not Singer or Painter, so C must be either Doctor, Teacher, or Dancer.
Step 2: Teacher, D, and A friendship.
Teacher and D prefer chapatti; A prefers rice. This tells us Teacher is not A. It also means Teacher must be either B, C, D, or E. But B is Painter, so Teacher is either C, D, or E.
Step 3: Doctor’s rice preference.
Doctor prefers rice, and among remaining candidates, C and E could fit that. But cross-check with chapatti preferences eliminates some possibilities.
Step 4: Narrowing to Dancer.
After assigning other roles logically from given constraints, the only role left for E is Dancer.
Therefore, \(\boxed{\text{E is the Dancer}}\).

Answer 3

We are given the same set of conditions from Q1 and Q2:
1. The five persons are A, B, C, D, and E, with the professions Singer, Dancer, Painter, Teacher, and Doctor.
2. A, C, and the Doctor prefer rice to chapatti. B and the Painter prefer chapatti to rice.
3. The Teacher, D, and A are friends, but two of them prefer chapatti to rice.
4. The Singer is C’s brother.
Step 1: Known assignments from Q1 and Q2.
From Q1: A is the Singer.
From Q2: E is the Dancer.
From the given preference data: A prefers rice, B prefers chapatti, and Painter prefers chapatti.
Step 2: Apply the friendship condition.
Teacher, D, and A are friends, and two of them prefer chapatti to rice.
We know A prefers rice, so Teacher and D must prefer chapatti.
Step 3: Who can be Teacher?
Teacher prefers chapatti, so Teacher cannot be A or C (both prefer rice).
Teacher must therefore be either B or D.
Step 4: Cross-check with Painter’s chapatti preference.
The Painter also prefers chapatti, but B is already confirmed to prefer chapatti. If D were Teacher, B would likely be the Painter, but then the other role distributions would not match the earlier deductions.
Testing the arrangement logically shows that B fits as Teacher without contradiction.
Step 5: Conclusion.
B is the only option that satisfies all clues for the Teacher role.
Therefore, \(\boxed{\text{B is the Teacher}}\).
