Answer 2

Answer:

The final answer is

1) The child with black hair is the girl

2) The child with white hair is the boy

Step-by-step explanation:

Given,

A boy and a girl are talking.

The child with black hair says " I am a boy".

The child with white hair says " I am a girl".

We know that atleast one of them lied. We need to find who the boy and girl are.

Since we have been given that atleast one of them lied. This means that there is the possibility that exactly one person has lied. Lets assume the child with black hair lied hence the black hair child would be a girl. This would mean that the child with white hair is a boy however this contradicts with the statement by the child with the white hair. This statement would only be true if there were only 2 boys or 2 girls. Hence, we come to a conclusion that both of them are lying hence,

Child with black hair is a girl.

Child with White jair is a boy.
