Ariana is the sister and Jane is the girlfriend.

Suppose if Ariana is his sister and we know that his statement is false.
This will mean that Myrna is not his girlfriend.
If Angelina is telling the truth, then Ariana must be lying that we have already assumed.

If Jane is his girlfriend, then she must have spoken a lie as well.
This will mean Angelina is speaking the truth which is true in what we have assumed.

At last, Myrna said that Jane is not his sister which is also true as we have made the assumption already that Jane is his girlfriend.

In what we have assumed, all the statements fit perfectly and the given conditions are satisfied. If you make any other assumption, you will find that one or more conditions are not fulfilled.

a) Jacob"s wife"s sister"s husband"s mother"s son is Patrick"s cousin"s father.
b) Sia"s grand-daughter"s cousin"s father"s sister-in-law is Gerry"s son-in-law"s wife.

Now if Annabelle has no children, what relationship does she share with Michael?

PS: There can be two solutions to this problem.

View Answer Discuss

Solution 1:
Annabelle is Michael"s daughter. This is because Michael is Sia"s son. Also he is married to one of the Gerry"s daughters. Gerry"s other daughter is married to Jacob and Patrick is their son.

Solution 2:
Michael and Jacob are brothers. Sia is their mother. In this case, "Jacob"s wife"s sister"s husband"s mother"s son" refers to Jacob himself. Thus, Patrick is Michale"s son and Annabelle is Jacob"s daughter which means that Annabelle is Michael"s niece.
