Read the following information carefully and answer the question which follows:
‘$$A \times B $$’ means ‘$$A$$ is the father of $$B$$’.
‘$$A+B$$’ means ‘$$A$$ is the daughter of $$B$$’.
‘$$A \div B$$’ means ‘$$A$$ is the son of $$B$$’
‘$$A-B$$’ means ‘$$A$$ is the sister of $$B$$’
What will come in place of question mark to establish that $$P$$ is the son-in-law of $$S$$ in the following expression ?
$$P \times Q+R-T?S$$
From the expression $$P \times Q+R-T$$ we can make deductions as:
P is father of Q. Q is daughter of R. Hence, P and R are husband and wife.
Also, R is sister of T. Hence, R must be daughter or son of S for P to be son in law of S.
Hence, the correct option is E
