Question

# If ‘A+B′ means 'A is the brother of B', ′A−B′ means 'A is the sister of B', ′A×B′ means 'A is the wife of B', and ′A÷B′ means 'A is the father of B', then which of the following indicates 'S is the son of P'? P×Q÷R+S−TP×Q÷R−T+SP×Q÷S−R+TP×Q÷R−S+TNone of these

Solution

## The correct option is D P×Q÷R−S+TAs `S' is a female in options (a) and (b), they can be rejected directly. The sex of 'S' in option (c) is not known, hence, it can also be eliminated. Now, check option (d). Clearly, S is the son of P.
