In a class there are seven students (including boys and girls) A, B, C...
To determine the number of girls among the seven students, let's analyze the given information:
● There are three benches: I, II, and III.
● Each bench must have at least two students.
● Each bench must have at least one girl.
From the given information, we can make the following deductions:
● C, who is a girl, does not sit with A, E, and D.
● F, a boy, sits only with B.
● A sits on bench I with his best friends.
● G sits on bench III.
● E is the brother of C.
Let's analyze the deductions one by one:
● C does not sit with A, E, and D. This means that C cannot be on bench I with A and cannot be on bench III with G. Therefore, C must be on bench II.
● F, a boy, sits only with B. Since F is with B and C is on bench II, F cannot be on bench I or bench III. Therefore, F must be on bench II with C.
● A sits on bench I with his best friends. Since A is on bench I and F is on bench II, G must be on bench III.
Based on the deductions, the seating arrangement looks like this:
Bench I: A and his best friends (unknown gender)
Bench II: C (girl) and F (boy)
Bench III: G (unknown gender)
From the given information, we know that at least one girl must be on each bench. Since bench II has C, a girl, and bench III has G (gender unknown), bench I must also have at least one girl to fulfill the requirement.
Therefore, among the seven students, there are either three or four girls. We cannot determine the exact number of girls as the gender of A and G is not provided.
Hence, the correct answer is option 'B' (3 or 4).

In a class there are seven students (including boys and girls) A, B, C...
Given information:
- 7 students (boys and girls) - A, B, C, D, E, F, and G
- They sit on three benches - I, II, and III
- At least two students on each bench and at least one girl on each bench
- C (girl) does not sit with A, E, and D
- F (boy) sits with only B
- A sits on bench I with his best friends
- G sits on bench III
- E is the brother of C
To find: Number of girls out of these 7 students
Solution:
1. C does not sit with A, E, and D. Therefore, C can sit only with B, F, or G.
2. F sits with only B. Hence, C cannot sit with F.
3. A sits on bench I with his best friends. Therefore, A cannot sit with C.
4. G sits on bench III. Therefore, C can sit only with B.
5. E is the brother of C. Therefore, E cannot sit with C.
Possible seating arrangements:
- Bench I: A and 2 girls (excluding C and E)
- Bench II: B, C, and 1 more student (boy or girl)
- Bench III: G, E, and 1 more student (boy or girl)
Now, we can consider the possible cases of seating arrangements:
Case 1: Bench II - 2 girls (including C)
- In this case, bench I should have 1 girl (excluding C and E) and bench III should have at least 1 girl (excluding E).
- Possible seating arrangements for bench I: AGx, AxF, AxG (where x represents a girl other than C and E)
- Possible seating arrangements for bench III: ExGy or GExy (where x and y represents a boy or a girl other than C and E)
- Therefore, there are 3 possible arrangements in this case - AGx, AxF, and AxG. But only the first two arrangements have at least two students on each bench. So, we can consider only those two arrangements.
- In both these arrangements, there are 3 girls (including C).
Case 2: Bench II - 3 girls (including C)
- In this case, bench I should have at least 1 boy and bench III should have at least 1 boy.
- Possible seating arrangements for bench I: ABx, ADx, or AFx (where x represents a boy or a girl other than E and C)
- Possible seating arrangements for bench III: GExy or ExGy (where x and y represents a boy or a girl other than E and C)
- Therefore, there are 6 possible arrangements in this case. But only the arrangements ABx-BCG, ABx-CEG, ADx-BCG, and ADx-CEG have at least two students on each bench. So, we can consider only those four arrangements.
- In all these four arrangements, there are 3 or 4 girls (including C).
Therefore, there are either 3 or 4 girls out of these 7 students.
Answer: Option (B) 3 or 4.
- 7 students (boys and girls) - A, B, C, D, E, F, and G
- They sit on three benches - I, II, and III
- At least two students on each bench and at least one girl on each bench
- C (girl) does not sit with A, E, and D
- F (boy) sits with only B
- A sits on bench I with his best friends
- G sits on bench III
- E is the brother of C
To find: Number of girls out of these 7 students
Solution:
1. C does not sit with A, E, and D. Therefore, C can sit only with B, F, or G.
2. F sits with only B. Hence, C cannot sit with F.
3. A sits on bench I with his best friends. Therefore, A cannot sit with C.
4. G sits on bench III. Therefore, C can sit only with B.
5. E is the brother of C. Therefore, E cannot sit with C.
Possible seating arrangements:
- Bench I: A and 2 girls (excluding C and E)
- Bench II: B, C, and 1 more student (boy or girl)
- Bench III: G, E, and 1 more student (boy or girl)
Now, we can consider the possible cases of seating arrangements:
Case 1: Bench II - 2 girls (including C)
- In this case, bench I should have 1 girl (excluding C and E) and bench III should have at least 1 girl (excluding E).
- Possible seating arrangements for bench I: AGx, AxF, AxG (where x represents a girl other than C and E)
- Possible seating arrangements for bench III: ExGy or GExy (where x and y represents a boy or a girl other than C and E)
- Therefore, there are 3 possible arrangements in this case - AGx, AxF, and AxG. But only the first two arrangements have at least two students on each bench. So, we can consider only those two arrangements.
- In both these arrangements, there are 3 girls (including C).
Case 2: Bench II - 3 girls (including C)
- In this case, bench I should have at least 1 boy and bench III should have at least 1 boy.
- Possible seating arrangements for bench I: ABx, ADx, or AFx (where x represents a boy or a girl other than E and C)
- Possible seating arrangements for bench III: GExy or ExGy (where x and y represents a boy or a girl other than E and C)
- Therefore, there are 6 possible arrangements in this case. But only the arrangements ABx-BCG, ABx-CEG, ADx-BCG, and ADx-CEG have at least two students on each bench. So, we can consider only those four arrangements.
- In all these four arrangements, there are 3 or 4 girls (including C).
Therefore, there are either 3 or 4 girls out of these 7 students.
Answer: Option (B) 3 or 4.
