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.

Arfath said: (Nov 19, 2010) | |

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. 1) A F B E D G C OR 2) A E D F B G C 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) | |

@Anish. 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. So, 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. "Friends". |

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. AE CFB GD AD CFB GE AFB ED GC AED FB GC |

Swetha said: (Feb 28, 2018) | |

@Puneet. 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. |

Shubham said: (Dec 10, 2019) | |

A sits on the bench I with his best friends acc to question they say A sits with HIS best friend his means A is a male member obvious. |

Maha said: (Jul 15, 2020) | |

Yes, A is the right option. |
