Logic Riddle Answer:
Statement 4 is false.
There are 3 men, 8 women and 6 children at the party.
How is the answer derived ?
Let’s tackle it via logical elimination method.
Assume that all three statements 4, 5, 6 are true.
Then statement 1 is false.
But both statements 2 and 3 cannot be true either, thus we
can conclude that one of the three statements 4, 5, 6 must be
false and all three statements 1, 2, 3 are true.
From statements 1 and 2, we know that there are 11 men and women.
Then from statement 3, there are 2 possibilities,
either there are 8 men and 3 women or 3 men and 8 women.
If there are 8 men and 3 women, then there is only 1 child (statement 2)
which will make both statements 4 and 5 false. We know that only one
statement is false, hence this possibility is eliminated.
If there are 3 men and 8 women, it will mean that there are 6 children
(statement 2). Bingo!! Statement 4 is false.
