(i) P ψ Q means P is mother of Q
(ii) P ∈ Q means P is sister of Q
(iii) P $ Q means P is father of Q
(iv) P # Q means P is brother of Q
Which of the following means N is definitely daughter of K?
🎥 Video solution / Text Solution of this question is given below:
In (B), $M \psi K$ ⇒ $M$ is mother of $K$.
$K $ N$ ⇒ $K$ is father of $N$.
$N \in L$ ⇒ $N$ is sister of $L$ ⇒ $N$ is female.
So $N$ is female child of $K$ ⇒ daughter.
