PostSubject: monks and cannibals   Tue Sep 19, 2006 3:46 pm

Here's a riddle 4 u doods, figure it out, cuz im totally stumped!
There's a group of 3 monks need to cross the river to get to their temple, but then comes a group of 3 cannibals, they also need to cross the river to go back to their village, now here's the problem, there's just one boat, and the boat can only hold 2 persons at a time, and there's another problem, the number of monks can't be outnumbered by the number of cannibals, or else, u know what would happen......
Now determine how many trips it will take to safely transport all of the monks and cannibals across the river, list each of the trips that need to be made and who is on the boat and who is on each of the riverbanks during each trip.
Note: the cannibals know how to row the boat, so it doesnt have to be a monk who rows the boat for them.

ok i'm gonna tell u how to cross!!

- first, 2Monks cross the river, 1 stays and the second one come to pick up an other. (2 trips)
- second, the return pick an other Monk and come backs, so 2 Monks crossed. (2 trips)
- third, the last Monk in the boat pick a carnibal and cross the river, but this time the Monk get off and the Carnibal comes back, so 3 monks crossed(2 trips).
- fourth 2 Carnibals cross and both of tem get off, and on of the 3 monks takes the boat to pick the last Carnibal, so 2Monks and 2 Carnibals crossed(2 trips).
- fith, the last Monk and the last Carnibal cross together, all the monks and carnibals crossed the river (1 trip).

total of trips: 9 trips.

waiting for correction.

sorry to interrupt Napole.. But when u do the 1st trip, u already dead...
u left that poor monk alone with 3 Canibals..

Maybe u think that its okay to left the monk behind because u knew that the 3 Canibals are vegetarian...??? lol!

lol, even the 1st step is wrong, one monk that stays will be devoured by the cannibals, cuz he's outnumbered, rite?

3 cannibals: C1, C2, C3
3 monks: M1, M2, M3
River has 2 sides: A and B
Suppose they wanna go from A to B

C1 and C2 go to B, C2 comes back
C2 and C3 go to B, C3 comes back
M1 and M2 go to B, C2 comes back
M3 and C2 go to B, C2 comes back
C2 and C3 go to B.

Done!

Try this: HAPPY-AND-SWEET family

A family has 7 members and a tiger
Dad
Mom
Son1
Son2
Daughter1
Daughter2
A fierce tiger
A bodyguard
They also wanna cross a river and there's only one boat that can carry 2 persons at a time. Well the tiger also uses up a person's load.

There are only 3 persons can row the boat: Dad Mom and the Bodyguard.
If Dad is not here, Mom will kill both sons.
If Mom is not here, Dad will kill both daughters.
If the Bodyguard is not here, the tiger will kill whoever near him.

How would you arrange their route to let all of them cross the river safely?
(safely = no one gets killed)
