There are at least two kangaroos in the enclosure.
One of them said: "There are 6 of us here" and he jumped out of the enclosure.
Afterwards, every minute one kangaroo was jumping out of the enclosure saying: "Everybody who jumped out before me was lying."
This continued until there were no kangaroos left in the enclosure.
How many kangaroos were telling the truth?
There are two possible cases:
1. If the first kangaroo was telling the truth, then there were six kangaroos in the enclosure. The second kangaroo must then be lying because he said, "Everybody who jumped out before me was lying." Similarly for the third, fourth, fifth and sixth kangaroos.
So, in this case, only one kangaroo (the first) was telling the truth.
2. If the first kangaroo was lying, then the second kangaroo must have been telling the truth. Then there must be at least one more kangaroo and he must be lying since he said, "Everybody who jumped out before me was lying." If there are any more kangaroos after that, then they must also be lying.
So, in this case, only one kangaroo (the second) was telling the truth.
In either case, only one kangaroo was telling the truth.
