The worlds first riddle!

Ah. For some reason I was trying to sum the results of each week.

10101 x 0 = 9.5 x 0

Eddie got a fancy new digital watch for Christmas but he couldn't figure out how to set it. He figured out that his new watch was 5 hours and 38 minutes slow. If the correct time is, 2:16 what time does his watch say

150 years ago there lived a king of ill heart and much pride. He had a daughter, whom he had promised to a rich neighbour, but she had a different plan: she fell in love with a plain lad, a blacksmith named Cho. The lovers tried to run to the mountains but were caught.

Angered, the king decided to execute Cho. However, not to appear as a cruel tyrant before his daughter and the people, and to show the blacksmith as intellectually unworthy for marriage to royalty, he let Cho decide his own execution based on his wits. The next day he had Cho placed in a room with nine doors. Each door led to a single room. One of the rooms contained the princess while the rest of the rooms were either empty or contained a tiger. Above each door was a sign.

Here's a list of the signs:

• Room I: The lady is in an odd-numbered room.

• Room II: This room is empty.

• Room III: Either sign on Room V is right or sign on Room VII is wrong.

• Room IV: Sign on Room I is wrong.

• Room V: Either sign on Room II or sign on Room IV is right.

• Room VI: Sign on Room III is wrong.

• Room VII: The lady is not in Room I.

• Room VIII: This room has a tiger and Room IX is empty.

• Room IX: This room has a tiger and sign on Room VI is wrong.


The king told Cho, "The sign on the door of the room containing the princess is true; the signs on the doors of all the rooms containing the tigers are false; while those on the empty rooms can be either true or false."

The king even gave Cho a hint and told him whether Room VIII was empty or not. If Cho was intelligent and worthy, he should be able to find the princess.

Behind which door is the princess

PRINCESS
I think the king told Cho that Room VIII was not empty, so the princess is in Room VII.

Salut Tryagain!

Tes mots sont correctement écrits même s'ils sont un peu dans le désordre.

Pour ce qui concerne les exercices, je laisse travailler tes élèves!

wait me

What can a man do standing up, a woman do sitting down, and a dog do on three legs >>>>urination

the lady

confusion
Room VIII: This room has a tiger and (((((((Room IX is empty))))))))>>>> half the sign is right and the other half is wrong?

i think the lady is in room IV

the room VIII is empty

"Room VIII: This room has a tiger and Room IX is empty."

If the king says Room VIII is not empty, then it must contain a tiger (if it contained a lady, then its sign would be false, but the sign on her room must be true). Since it contains a tiger, the sign on Room VIII must be false. Thefore, "Room IX is empty" is false.

For an 'and' statement to be true, both parts must be true. If either or both parts are false, then the statement is false.

thanks marker

if we say that an "either" statement is false
that means to inverse bothe parts?

usamashaker:
"if we say that an "either" statement is false

I treated "either or" as an 'or' statement and not an 'xor' (exclusive or) statement. If an 'or' statement is false, then the opposites of both parts are true. If an 'xor' statement is false, then both parts are true or the opposites of both parts are true.

Jon knows he needs at least an 85% on his next test to raise his average to 90%. He looks and sees that the test has 30 questions.

What is the minimum number of questions he must answer correctly

is this riddle true?

or you mean he needs 90% at least to raise his average to 85 %

so the answer will be 27
