Q & A
How many keys are mentioned in the transcript and what is the maximum number of attempts needed to figure out the key for each door?
-There are three keys mentioned in the transcript. The maximum number of attempts needed to figure out the key for each door varies: 3 attempts for the first door, 2 attempts for the second door, and 1 attempt for the last door.
What is the solution to the chain puzzle mentioned in the transcript?
-To make a long chain out of the five pieces of chain with three links each and with only $15, the solution is to break open one piece of chain, costing $3, and use the open links to connect the remaining four pieces. Welding these links will cost another $9, making the total cost $12.
How can eleven thousand, one hundred and eleven be written in digits?
-Eleven thousand, one hundred and eleven can be written as 11,111 in digits.
What is the solution to the river crossing riddle mentioned in the transcript?
-To cross the river with nine numbers from one to nine, trips need to be made as follows: 2 + 5 + 9 = 16 (then nine returns), 3 + 4 + 9 = 16 (then nine returns), 1 + 7 + 8 = 16 (then one returns), and finally, 1 + 6 + 9 = 16.
What are the ages of the person and their son mentioned in the transcript?
-The person is 40 years old, and their son is 10 years old.
What number is described in the transcript where the second digit is four times as big as the first one, and the third digit is smaller by three than the second?
-The number described in the transcript is 141.
In the Lily pond riddle, in how many days will the Lily cover half of the pond?
-The Lily will cover half of the pond on the ninth day.
How can you turn 98 into 72 by using just one letter?
-You can turn 98 into 72 by adding the letter 'X' between nine and eight, making it 9X8 = 72.
What is the solution to the light bulb riddle mentioned in the transcript?
-To determine which switch is connected to which light bulb, turn on the first switch and leave it on, then do not touch the second switch but turn on the third switch. After a few minutes, turn off the third switch. When entering the room, one light bulb will be brightly lit (connected to the first switch left on), one light bulb will be off and cold to the touch (connected to the second switch never touched), and the last light bulb will be off but warm to the touch (connected to the third switch turned off after being turned on).
How is the extra dollar accounted for in the hotel room expense riddle mentioned in the transcript?
-The extra dollar is a result of incorrect arithmetic. The friends' calculation of $27, which is $25 for the room and $2 tip, is misleading. It's a mathematical trick that doesn't accurately represent the expenses. The correct way to calculate their expenses would be $25 for the room and $3 tip, totaling $28, not $27.
