140. Gen. McArthur, His Sister, His Son, His Daughter Are Fond of

General MacArthur, his sister, his son, and his daughter all play volleyball.
These two statements are true:
(1) The best player’s twin and the worst player are of opposite sexes.
(2) The best player and the worst player are the same age.

Question: who is the best player?

Submitted by tartle · Added 24 June 2011

Solution: Answer: General MacArthur’s daughter.

Why:

The daughter’s twin is General MacArthur’s son, who is male.
The worst player must therefore be female.
The worst player is also the same age as the best player.


So the worst player is General MacArthur’s sister, who is the same age as the daughter.


That leaves the daughter as the best player.

His daughter is the best player and his sister is the worst player (and his sister is the same age as his daughter).

(1) the best players twin and d worst player are of opposite sex;
assume best player is among son and daughter. And the worst player is among him and his sister.

(2) the best player and the worst player are of the same age.
Only combination is his sister and his son or daughter. So the Worst player is Sister and the best can only be hi Son(because best and worst are opposite sex)

Ans may be - Son - Sis

How comes , check this:-

McArthur - Sis
McArthur - Daughter
Son - Sis
Son - Daughter

2. the best player and the worst player are of the same age, So possible combinations are -

McArthur - Sis
Son - Sis
Son - Daughter

3. Best player are twins

McArthur - Sis(Its not possible because then best player dont have twin then)
Son - Daughter(Its not possible because then best player dont have twin then)
Son - Sis(Its correct ans)
