A man is the owner of a winery who recently passed away. In his will, he left 21 barrels (seven of which are filled with wine, seven of which are half full, and seven of which are empty) to his three sons. However, the wine and barrels must be split so that each son has the same number of full barrels, the same number of half-full barrels, and the same number of empty barrels.

Three men in a cafe order a meal the total cost of which is $15. They each contribute $5. The waiter takes the money to the chef who recognizes the three as friends and asks the waiter to return $5 to the men.
The waiter is not only poor at mathematics but dishonest and instead of going to the trouble of splitting the $5 between the three he simply gives them $1 each and pockets the remaining $2 for himself.
Now, each of the men effectively paid $4, the total paid is therefore $12. Add the $2 in the waiters pocket and this comes to $14…..where has the other $1 gone from the original $15?

The king had his doubts about his sons’ fighting
skills, and so he sent his two eldest to the court magidan
for potions to help fight the ogre.
The magician kept his magic hidden, mindful of the
danger of his potent potion falling into the wrong
hands. In a secret but inconvenient compartment in his
laboratory, he hoarded:
1. four ogre-fighters
2. three dragon-destroyers
3. two evil wizard-vanquishers
How many potions did he have to reach for in order
to make sure that he could give an ogre-fighter to each
of the king’s two sons?View SolutionSubmit Solution- 1,528.7K views

Hostile members of the Uti, Grundi and Yomi groups
were travelling to a conference. There were two members
from each group, one finned and one feathered.
The finned Martian was much stronger, and had to
protect her feathered friend. Never could a feathered
Martian be left alone with a finned Martian of another
group. The only time a feathered Martian was safe with
the finned Martian of another group was when the
feathered Martian of that enemy group was also
present.
The trip was quiet until they came to a deep ravine.
The only way to cross it was by swinging across on a
rope. But the rope was only strong enough to hold two
of them. And it wasn’t heavy enough for them to swing
it back over the ravine without someone to weigh it
down. How did they all cross the ravine?View SolutionSubmit Solution- 1,530.6K views
