In a class there are seven students (including boys and girls) A, B, C, D, E, F and G. They sit on three benches I, II and III. Such that at least two students on each bench and at least one girl on each bench. C who is a girl student, does not sit with A, E and D. F the boy student sits with only B. A sits on the bench I with his best friends. G sits on the bench III. E is the brother of C.
How many girls are there out of these 7 students ?
Answer: Option B
The number of girls is either 3 or 4.

|There can be only Three girls as E is stated to be brother of C.|
|Ankita said: (Dec 18, 2010)|
|How option b is right?|
|Ritesh said: (Feb 1, 2011)|
|I think option A is right.|
|Divya said: (May 18, 2011)|
|Where it is mentioned that 'd' is a girl and 'a' is a boy.|
|Anselam said: (Jun 1, 2011)|
|A sits on the bench I with 'his' best friends. E is the 'brother' of C. This means A & E are boys so by default D is a girl because atleast one girl sits on each bench.|
|Anselam said: (Jun 1, 2011)|
|In the question if it is said thad that atleast 1 boy sits on each bench then G would be a boy. Since nothing like this is mentioned it cannot be determined that G is a boy or girl. Also no his or her term is mentioned with G in any sentence of the question.|
|Harsha said: (Nov 2, 2011)|
|How can we say that B is girl?|
|Krishna said: (Dec 9, 2011)|
|How them take 'D' is a girl?|
|Ravi said: (Aug 7, 2012)|
|According to the question, A sits on the bench 1 and G sits on the bench 3. Since F the boy student sits with only B, so place F and B on the bench 2. Because F is a boy, B must be a girl. Given that, C (girl) can not sit with A, E and D so place it on bench 3.
Given that, A sits on the bench I with his best friends. Therefore more then two students are sitting on bench 1, which are A, E and D. Because A and D are boys, so E is a girl.
G may be a boy or girl.
Answer (b) is correct.
|Sid said: (Mar 3, 2013)|
|E is the the brother of C so how can E become a girl ?|
|Bikram said: (Mar 8, 2013)|
|But the question is still not clear that A, E and D has to b in the same bench. How could we derive to this conclusion, can anyone explain please?|
|Anish said: (May 3, 2013)|
|Let me help you out.
There is 2 possible answers.
A F B
A E D
In any arrangement we know C is a girl.
A is a boy as in question it is told "his friends".
E & F are boys .
Take 1st arrangement.
A, F boys & B shd be girl.
E a boy & D shd be girl.
G Can be girl or boy bt C is girl.
i.e Total 4 girls.
But similarly try 2 arrangement you will turn up with 3 girls.
Hence 3 or 4 girls.
|Naren said: (Oct 9, 2013)|
F the boy student sits with only B(It means that FB can occupy only 2 row). Since we don't know whether G is he or she .. So no of girls could be 3 or 4.
|Teja said: (Oct 22, 2013)|
|Let me explain this answer.
1) A seat with "his" "friends"
i.e., A is boy and 1st bench has 3 students.
2) F seats "only" with B.
Given F is boy and i.e., B is girl.
3) G is 3rd bench remaining student is C.
Males are f, e, a.
So answer is 3 or 4.
|Krishna said: (Oct 24, 2013)|
|F Is a Boy Hence male Given.
E Is Brother Hence Male Given.
A Sits With HIS Best Friends Given (HIS Used For A Hence Male).
So It Is Clear That 3 Are Male.
Total no.of Students Are 7,
So There May Be 3 Or 4 Girls.
|Jayant said: (Mar 17, 2014)|
|As per my conclusion G could be Male or female so answer B is right.|
|Vijay Shanker Sahu said: (Jun 10, 2014)|
|There is exact three girls because A is sit with his friend. It means A is a male and E is male So BCD are only females.|
|Prem Kumar said: (Aug 9, 2014)|
|Option B is right.
it's obvious that there should be 3 girls ....a/c to ques.
And it's clear that boys E, F, A(sits with his friend).
One member can be either girl or boy.
So, there should be either 3 or 4 girls.
|Pravin said: (Sep 4, 2014)|
|Sorry its right 3/4 bcs there is nothing given about the gender of g so 3/4.|
|Praveen said: (Oct 2, 2014)|
|According to the question, A sits on the bench 1 and G sits on the bench 3. Since F the boy student sits with only B, so place F and B on the bench 2. Because F is a boy, B must be a girl. Given that, C(girl) can not sit with A, E and D so place it on bench 3.
Given that, A sits on the bench I with his best friends. Therefore more then two students are sitting on bench 1, which are A, E and D.
Since E is the brother of C. E is a boy.
In bench 1 min one person should be girl, but we don't no about A &D.
girls=C ,B confirmed and more 1 or 2 persons from A ,D are girls.
Therefore answer is (B).
|Devi said: (Oct 11, 2014)|
|How is A a male member and D a female member?|
|Desk said: (Nov 11, 2014)|
|A is male member because its mentioned in question:
A sits on the bench I with his best friends.
D is a female member because at-least one girl should be sitting on a bench.
|Kartik Mehta said: (Nov 17, 2014)|
|I II III.
A-B Yes No No C (x).
B-G No Yes No.
C-G No No Yes A-E-D (x).
D-G Yes No No.
E-B (his) Yes No NO.
F-B No Yes NO.
G-B NO No Yes.
3 People 2 People 2 People.
|Divya said: (May 4, 2015)|
|Why it is 3 or 4? Why not 3 only? If its clearly mentioned about the boys here.|
|Nandini said: (May 29, 2015)|
|Because its not clear whether G is a girl or boy. It is said that there has to be at least 1 girl but not necessarily 1 girl only on each bench. And G's gender is not specified. So there is 3 or 4 girls.|
|Naveed Ullah said: (Oct 7, 2015)|
|If the arrangement is like that:
Bench 1: A, D.
Bench 2: F, B, C.
Bench 3: G, E.
Then below all question get wrong, is it possible arrangement please.
|Nivesh Agrawal said: (Jul 7, 2016)|
|3 girls should be there definitely because A is a boy because his word is used for A, and his represent a boy.|
|Shrey said: (Aug 5, 2016)|
|Since A is sitting with his best friends which means more than one so 3 people will be sitting on first bench. F is a boy so B has to be a girl as only two two students will sit on 2 and 3 bench. C can not sit on bench 1 and bench 2 is occupied by F and B so it sits on bench 3. Rest can be figured easily.|
|Manoj Jangir said: (Sep 9, 2016)|
|Answer (b) is correct as we can clearly see there are three girls (d, b, c) definitely but we can't make out G is a girl or a boy. So the answer (b) 3/4 is correct.
The arrangement can be made easily but a number of girls and boys is little tricky.
|Mihir said: (Oct 7, 2016)|
|It can also be 1) AFB, 2) ED, 3) GC.|
|Anand said: (Oct 14, 2016)|
|According to me, The question is in wrong format. It should have been, how many girls can we assume out of 7? Otherwise, the answer is data inadequate.|
|Karthik said: (Dec 20, 2016)|
|According to me, the solution is;.
Consider this, " A sits on the bench I with his best friends" means A is a boy "E is the brother of C " means E also is a boy. That leaves with only "3" girls - can't be 4 girls.
|Zorama said: (Apr 21, 2017)|
|There can be only three girls as we see that the pronoun for A is written as 'his'. So, option A is correct one. If not, you will face another problem in one of the next questions about a group of girls which is having its answer as CBD.|
|Prem Kumar said: (Jun 27, 2017)|
|Indirectly given that A sits with HIS best friends which means A is a male and D is the only female in the 1st row.|
|Puneet said: (Jan 23, 2018)|
|4 arrangements are possible.
|Swetha said: (Feb 28, 2018)|
You are right, 4 arrangements are possible.
|Arnab said: (Jul 31, 2018)|
|How to judge the gender of 'A' & 'D' ?|
|Pranaya said: (Sep 8, 2018)|
|'G' may be male/female so option 2 is correct because B, C, D are girls that is final.|
|Ryngkat said: (Sep 16, 2018)|
|There should only be 3 female. It is mentioned that there should be at least 1 girl in a bench and it says a sits with 'his' best friends, i.e., E and D, E is said to be brother of C. Therefore D is the possible female.|
