- there are exactly 3 girls
lets denote all charcters with a,b,c,d,e,f,g
and trees with mah,oak n map
according to ques c is a girl & will not sit with a,e,d
f who is a guy sits only with b as there should atleast one girl on each table so b will be a girl.
since c cant sit with a,e,d she will sit with gaurav who is a guy
and a,e,d will sit together
from ques e is a guy
also from the language of the question it is clear that a is also a guy
so there will be 4 boys-a,e,f,g
3 girls-b,c,d
hence for second question is option D. - 10 years agoHelpfull: Yes(8) No(3)
