Dragon and the Knight Puzzle

[Admin]

A dragon and knight live on an island. This island has seven poisoned wells, numbered 1 to 7. If you drink from a well, you can only save yourself by drinking from a higher numbered well. Well 7 is located at the top of a high mountain, so only the dragon can reach it.

One day they decide that the island isn't big enough for the two of them, and they have a duel. Each of them brings a glass of water to the duel, they exchange glasses, and drink. After the duel, the knight lives and the dragon dies.

Why did the knight live? Why did the dragon die?

well thats my approach to the answer....

since both dragon and knight are enemies , they will try their best bet..

so dragon bring a glass from 7th well to which their is no antidote...

but now knight has trick ....

before coming to the duel he drinks a glass from the 1st well...

hence the glass from the 7th well given to him by dragon acts an antidote :-)

now how does the dragon die ....
dragon knows that knight can bring water from only 1-6 numbered wells
so it can drink a glass from 7th well after the duel to neutralize the effect ....


but knight is smart enough , he anticipates this and bring a glass of water from the SEA/OCEAN (after all they live on a island ;-) ) which is poison-less....

dragon unaware of this fact still drinks a glass from 7th well and dies....

hope thts justified and correct
