Question 106

Read the following information carefully and answer the question which follows:
If ‘A $$ \times$$ B’ means ‘A is the father of B’.
If ‘A $$+$$ B’ means ‘A is daughter of B’
If ‘A $$\div$$ B’ means ‘A is son of B’.
If ‘A $$-$$ B’ means ‘A is sister of B’.
What will come in the place of the question mark, to establish that P is the son-in-law of S in the expression ; ‘P $$\times$$ Q $$+$$ R $$-$$ T ? S

Solution

In the expression : P $$\times$$ Q $$+$$ R $$-$$ T ? S

P is the father of Q and Q is the daughter of R, => R is wife of P

Also, R is sister of T.

So, in order for P to be son in law of S, T must be the child of S

Now, both '+' and '$$\div$$' will fulfill the above condition because :

In case of '+', T is the daughter of S and in case of '$$\div$$' , T is the son of S.

So, in both cases, P is son-in-law of S.
