Q. Zulus always speak truth and Hutus always speak lies. There are three persons A, B & C. A met B and says " I am a Zulu or I am Hutu". We don't know what exactly he said. then B meets C and says to c that " A is a Zulu ". Then C replied " No, A is a Hutu ".

How many Zulus are there ?

Who must be a Zulu ?

• B is Zulu.....because A had said he is Zulu surely......beause if A is Zulu he would accept & if he is Hutu then also he would tell lies that he is Zulu...thus A may be Zulu or Hutu and B told truth so he is Zulu and C told lies so he is Hutu

• C for sure.Coz. If B were a zulu ,then he wouldnt have old C that A is zulu Coz A didnt made himself clear to B about himself.C might be knowing the truth and that may be why he replied A is HUTU.

• ZULU=2 and hutus= 1
  1) B is definitely zulu
  2) solution consists of two case
  3) 1st:- If C is zulu , A must be hutus where B is definitely zulu
  4) 2nd:- If C is hutus, A must be zulu where B is definitely zulu
  5) Both case have 2 zulu and one hutus. And so ZULU= 2.

• A and B are zulu as if a said he is a zulu then he is sayng truth but if he said he is a hutu he is a lier so he is lying and so he is a zulu . then b reports correctly tht aisa zulu and c is hutu as he lied.
