In a certain code language,R + T means ‘R is the sister of T’.R – T means ‘R is the father of T’.R T means ‘R is the wife of T’.R ÷ T means ‘R is the mother of T’.Based on the above, how is L related to S if ‘K – L ÷ P Q – R + S * T?

Let's break down the expression K – L ÷ P Q – R + S T step-by-step from left to right to build the family tree:K – L: K is the father of L.L ÷ P: L is the mother of P.P Q: P is the wife of Q (P is female, Q is male).Q – R: Q is the father of R.R + S: R is the sister of S (R and S are siblings, both children of Q and P).S T: S is the wife of T (S is female).Now, let's track the relationship between L and S:S's mother is P.P's mother is L.Therefore, L is the mother's mother (maternal grandmother) of S.
