Verbal Reasoning - Seating Arrangement - Discussion

How can we say that B is girl?

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.

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.

I think option A is right.

There can be only Three girls as E is stated to be brother of C.

3 girls should be there definitely because A is a boy because his word is used for A, and his represent a boy.

Sorry its right 3/4 bcs there is nothing given about the gender of g so 3/4.

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).

How is A a male member and D a female member?

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.
