Did you enjoy the Brain Teasers from the Issue 001? Were they challenging?
Let us go over the solutions of those.
Solution:
Opposite of
Red = Green
Yellow = Blue
Orange = Purple
Solution:
WEN IHLED is an anagram is "NEW DELHI"
July 1st = 1st letter of July = J
March 2nd = 2nd letter of March = A
June 3rd = 3rd letter of June = N
And so on, leads to "JANUARY"
26.9.50 = 26th Day of January (Republic Day)
09:50 = Time of the Day
So, answer is 26th January, 9:50, New Delhi
Solution:
If you convert the given sequence in the roman numerals, you will get a Palindrome.
1 4 3 5 10 2 6 9 8 7
I IV III V X II VI IX VIII VII
If you read above Roman Numerals, from backwards or forwards, it's the same. Hence, a Palindrome.
Solution:
Notation.
Let
S = “Today is Sunday.”
P = “The king will throw a party today.”
The king’s utterance can naturally be read as the conjunction — i.e. “It is Sunday and I will throw a party.”
Given.
“The king of the island always lies on the Sundays.” (Read naturally as: on Sundays the king lies; on non-Sundays he does not lie.)
Step 1 — Eliminate the possibility that the king was telling the truth when he spoke
If the king were telling the truth that day, then his statement would be true. That would mean is true (it is Sunday) and is true (he will throw a party). But the king always lies on Sundays, so he cannot be telling the truth on a Sunday. Contradiction.
Therefore he was not telling the truth when he made the statement.
Step 2 — Conclude what day it must have been
We assumed the king only lies on Sundays. Since he was not telling the truth when he spoke, that means he must have been lying — and therefore the day must be Sunday (the only days he lies).
So we now know the day is Sunday, and the king is lying.
Step 3 — Use that the king is lying to decide whether the party happened
He spoke the statement . On a Sunday that statement is false (because he is lying). But we already know is true (it is Sunday). For a conjunction to be false while is true, the other conjunct must be false. Hence is false.
So the king did not throw a party.
Final answer
No — the king did not actually throw a party that day.
