Question
Directions : A is mother of D who is father of G. B is grandfather of E and husband of A. D who has only two children is brother of C. A has two children both of same gender. J is aunt of H who is sister of G.At least how many male members can be predicted by the given relations?5243
Solution
Let's break down the relationships:
-
A is mother of D who is father of G. This means A is a female, D is a male, and G can be either male or female.
-
B is grandfather of E and husband of A. This means B is a male, E can be either male or female, and A is confirmed as female.
-
D who has only two children is brother of C. This means D is confirmed as male, C can be either male or female, and D's two children can be either male or female.
-
A has two children both of same gender. Since we know one of A's children, D, is male, this means the other child (C) is also male.
-
J is aunt of H who is sister of G. This means J is a female, H is a female, and G is confirmed as male (since H is his sister).
So, from the given relations, we can confirm at least three male members: B, D, and C. G is also male. So, we have at least 4 male members.
