In a certain code language,
‘A + B’ means ‘A is the mother of B’,

‘A – B’ means ‘A is the father of B’,

‘A × B’ means ‘A is the daughter of B’.

Based on the above, how is H related to L if ‘H + I – J × K + L’?

Let's decode the given relationship string step-by-step from left to right:
H + I: H is the mother of I (H is Female).

I – J: I is the father of J (I is Male).

J × K: J is the daughter of K (J is Female). Since I is the father of J, K must be the mother of J, which means I and K are husband and wife.

K + L: K is the mother of L (K is Female). Since I and K are married, L is also the child of I and K.

Now let's trace the relationship between H and L:

I is the father of L.

H is the mother of I.

Therefore, H is the father's mother (paternal grandmother) of L.
