Answer 1

when Two kids are liars, three can only say the truth. Jane: " Julia is only a liar, if John is telling the truth." Julia: "If Joey doesn’t lie, then either Jane or John do." Joey: " Jack lies, as does Jane or Julia." John: "If Julia is telling the truth, then Jane or Joey do as well." Jack: "If you round up Jane, Joey and John, you will have at least one liar."

then

The compulsive liars are julia and jack

Julia and jack is fit in blank

because julia is only a liar .

jack lies as does Jane or Julia." John: "If Julia is telling the truth, then Jane or Joey do as well."

Answer 2

John and Jack are the compulsive liars in this situation.

If we study the statement correctly then Joey said that Jack is a liar which will mean that one of them is a liar.

If we check the statement given by Jack then you can clearly see that Jane, Joey and Julia are honest that will contradict the condition of Joey.

Hence, jack is a liar. Hence, joey is not a lair said by Julia making her honest. But this is contradicting John’s statement-making him a liar.
