Well, I don’t addict this computer things, so I’m going to contribute with my part. And, how the title says, today I’m telling you some riddles:
The berber will
A berber from the desert has three sons with different ages, and some camels. But, at his time, he passes away and leaves in his will an enigmatic statement. For distributing his 17 camels between his three sons, he puts two conditions:
- The first is the way the camels have to be distributed. The older son has to receive the half part of the total, the middle son must receive the third part and, the younger son, the ninth part.
Apparently, this is not a problem, because 17/2 = 8.5 camels, so if we kill a camel and divide it in halves, we could distribute correctly, but…
- The second condition says that they can’t kill, give, or do anything with the camels, so at the end of the distribution the total of camels has to be 17.
The sons, unable to solve this hard puzzle, decide to visit the town’s wise, and they ask him the solution.
How can we solve this problem?
The café
There’s a new café in town, and three friends arrange to go there and have a coffee, to see how good is it. They ask for 3 cups of coffee, and the waiter show them the bill. They have to pay 15 cents (The café was new, so there was low costs). When the waiter is going to put the money in the cash desk, the café’s owner tells him to pay back 5 cents to the customers, since they have been the first customers of the café. The waiter thought that it would be impossible to distribute 5 cents between three people, so he kept 2 cents and gave 3 cents to the friends. When the waiter gave them the money they kept 1 cent each one, and they go to their respective jobs, very happy with the services and the decoration of the café. But…
If they get back a cent, it’s like if they had paid 4 cents for each cup of coffee (remember that initially they worthed 5 cents, but each friend got back a cent). If we do a quick operation:
4 cent x 3 cups of coffee = 12 cents
12 cents + 2 cents (from the waiter) = 14 cents
¿Where’s the missing cent?
The mythical Einstein’s riddle
In a street there are five houses, painted five different colours. In each house lives a person of different nationality. These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.
We have the following hints:
- The Brit lives in a red house.
- The Swede keeps dogs as pets.
- The Dane drinks tea.
- The Green house is next to, and on the left of the White house.
- The owner of the Green house drinks coffee.
- The person who smokes Pall Mall rears birds.
- The owner of the Yellow house smokes Dunhill.
- The man living in the centre house drinks milk.
- The Norwegian lives in the first house.
- The man who smokes Blends lives next to the one who keeps cats.
- The man who keeps horses lives next to the man who smokes Dunhill.
- The man who smokes Blue Master drinks beer.
- The German smokes Prince.
- The Norwegian lives next to the blue house.
- The man who smokes Blends has a neighbour who drinks water.
¿Who’s the goldfish owner?
Sum… the letters?
Each letter has a numeric value (from 0 to 9). You have to guess them.
The words are in Spanish. It doesn’t really matter, but its translation is “six of january = kings“. In January 6th, in Spain it’s the Magi Kings‘ day.
The 3 bulbs
We have in front of us a two floor building. In the bottom floor, we have three switches: (A ; B ; C) and stairs that lead us to the top floor, in which there are three bulbs (1 ; 2 ; 3).
You, dear reader, as a good electrician, have to know which switch sets on which light bulb in an exact way and without theories. The difficulty is that you can only climb the stairs one time.
Notice that there is no cheating, no windows, there is no possibility of seeing the bulbs nor the light without climbing upstairs.
Example: I switch on A switch. When I go up in the top floor, I see that second lightbulb is open, so I can say that switch A lights bulb 2, but I can’t say what switch lights bulb 1, for example. So this is the reasoning to follow.
Good luck and see you the next day!
