Of Abdul, Binoy, and Chandini:
a)Each member belongs to the Tee family whose members always tell the truth or to the El family whose members always lie.
b)Abdul says ''Either I belong or Binoy belongs to a different family from the other two."
Whose family do you name of?
The data in question throws light on Binoy and Abdul only so we can guess the family of these two only
ReplyDeleteLet's see what this question is saying.At a quick workout if Abdul is true he belongs to Tee family and other two to the EI family on the other hand if he is false then he belongs to EI family and other two from TEE family.....Which is wrong.
Its a habit we try to understand the problem with partial knowledge and then derive at wrong results which is very dangerous.And that is why we sometimes fail to judge people :D Anyways lets look at the correct answer.
Abdul says "Either I belong or Binoy belongs to a different family from the other two."
So if he is speaking truth he belongs to TEE Family and Other two belongs to other family which is EI family Hence Benoy belongs to EI Family
If he is speaking a lie then They both belong to same family and Benoy again belongs to EI family so Abdul and Benoy both belong to EI family
Hence Answer is Benoy's Family which is EI
