In Leftwrite, every inhabitant is either a lefty or a righty. Lefties write true statements with their left hand and false statements with their right hand. Righties write false statements with their left hand and true statements with their right hand. An inhabitant wrote, "My father and I are both lefties." With the same hand, he wrote, "My father is a righty." What type is the inhabitant, what type is his father, and what hand did he write the statements with?
(In reply to
Puzzle Answer by K Sengupta)
Since the two statements were written with the same hand, it follows that:
Both the statements are true
Or, both the statements are false.
However statement-2 contradicts Statement 1.
This, both the statements cannot be true.
Accordingly, both the statements are false.
Thus, from false made statement-2, it follows that:
The father is a lefty.
In such a situation, statement-1 is false only when the inhabitant is a righty, who must have written with his left hand.
Consequently,
The inhabitant is a righty
His father is a lefty, and:
The inhabitant wrote with his left hand.
