SOME SIMPLE TRICKS

 (i) First of all choose the two persons, between whom relationship is to be established.

(ii) Next, pin-point the intermediate relationship i.e., such relationship through which long drawn relationship can be established between the required persons.

(iii) Finally, conclude the relationship directly between the two persons as per the requirement of the question.

(iv) From a particular name we cannot ascertain the sex (gender) of that person. The name does not always show the gender beyond reasonable doubt.
