Which of the following inferences is not true on the basis of the following equation?

$T \# L \$ M \$ P 1 J ∆ N n K$

If A $+$ B means 'A is the sister of B',

A $÷$ B means 'A is the wife of B',

A $\times$ B means 'A is the brother of B ',

A $-$ B means 'A is the mother of B',

Then which of the following expresses the relationship that 'P is the son of Q'?

'$P∆Q$' means '$P$ is the mother of $Q$'

'$P \gamma Q$' means '$P$ is the father of $Q$'

'$P \delta Q$' means '$P$ is the brother of $Q$'

'$P \alpha Q$' means '$P$ is the sister of $Q$'

$\mathrm{P} \# \mathrm{Q}$ means $P$ is the mother of $Q$,

$\mathrm{P} * \mathrm{Q}$ means $P$ is the sister of $Q$.

Then how is $Q$ related to $N$ in$\mathrm{N} \# \mathrm{L} \$ \mathrm{P} * \mathrm{Q}$?

If $A -B$ means $A$ is the sister of $B$

$A \times B$ means $A$ is the mother of $B$

$A÷ B$means $A$ is the brother of $B$

Which of the following means that '$M$ is the aunt of $K$'?

Given that

(i) '$A* B$' means '$A$ is the sister of $B$'.

(ii) '$A O B$' means '$B$ is the mother of $A$'. 

(iii) '$A+B$' means '$A$ is the brother of $B$'.

(iv) '$A=B$' means '$B$ is the father of $A$'.

Which of the following means '$M$ is the maternal uncle of $N$ '?

Pointing to a photograph, Y says, 'He is the only brother of the only daughter of my sister's maternal grandmother'. Pointing to another photograph, X says, 'He is the only brother of the only daughter of my sister's maternal grandmother'.
