In a certain code language,

'A + B' means ‘A is the father of B’,

'A – B' means ‘A is the husband of B’,

'A × B' means ‘A is the mother of B’,

'A ÷ B' means ‘A is the brother of B’.

How is P related to T if ‘P + Q – R × S÷T’?

The correct option is Father's father.

To determine how P is related to T in the given expression 'P + Q – R × S ÷ T', let us decode the relationships step-by-step from left to right based on the provided code language:

1. 'P + Q': 'A + B' means 'A is the father of B'. Therefore, P is the father of Q.

2. 'Q – R': 'A – B' means 'A is the husband of B'. Therefore, Q is the husband of R. This also implies that R is the wife of Q (meaning Q is male and R is female).

3. 'R × S': 'A × B' means 'A is the mother of B'. Therefore, R is the mother of S.

4. 'S ÷ T': 'A ÷ B' means 'A is the brother of B'. Therefore, S is the brother of T.

Now, let us combine these steps to find the relationship between P and T:

• Since R is the mother of S and S is the brother of T, R is also the mother of T.

• Since Q is the husband of R and R is the mother of T, Q is the father of T.

• Since P is the father of Q and Q is the father of T, P is the father of T's father.

Hence, P is the Father's father of T.
