iPad is mine
There are four friends Aqib, Bhupal, Craig and Dingbang.
It is known that two of them always speak truth (Knights), one always lies (Knave) and one may speak truth or lie (Jester).
One day, while in the shopping hall, a strange man came closer to them and showed them a lost ipad .
The strange man asked whether any one of them owned the ipad.
They gave the following statements,
Aqib: "I'm the owner"
Buphal: "Aqib is the owner"
Craig: "None of us is the owner"
Dingbang: " I'm the owner"
Did the Jester tell the truth or did he lie?
