Hello all,
here is a new difficult riddle for you. Have fun to find the answer.
Johanna and Joel have five children: Julia, John, Joachim, John and Jaqueline.
Two of the children are always lying, the other three are always telling the truth.
From the following conversation you can already conclude who the two liars are:
Julia: "John lies only when John tells the truth."
John: "If Joachim does not lie, then either Julia or John is a liar."
Joachim: "Jaqueline lies, and also Julia or Johannes lie."
John: "If John says the truth, then also Julia or Joachim tellin gthe truth."
Jaqueline: "There is at least one liar among the persons Julia, Joachim and John."
