A % B means 'A is the son of B'.A $Bmean{s}^{\prime }Aisthebrotherof{B}^{\prime }.A+Bmean{s}^{\prime }Aisthesisterof{B}^{\prime }.Iftheexpressionis$ N + T \$K\%M\%Y$, then how is N related to Y?

Let's break down the relationship expression N + T \ K \% M \% Y$stepbystepfromlefttoright:N+T:NisthesisterofT($ N\,[\text{Female}] \rightarrow T$).T$ K: T is the brother of K ($T[\text{Male}]\to K$). Thus, N, T, and K are siblings.K % M: K is the son of M ($M\to K[\text{Male}]$). Since N, T, and K are siblings, M is the parent of all three.M % Y: M is the son of Y ($Y\to M[\text{Male}]$). This means M is the father of N, T, and K.We need to find how N is related to Y:M is N's father, and Y is M's parent.Since N is a female, N is the granddaughter of Y via her father's side.Therefore, N is the Paternal granddaughter of Y.
