Proper share

A person, on his death bed, leaves a will stating that if he is blessed with a baby boy, he should inherit 2/3 of the estate and 1/3 should go to his mother (i.e.his wife). On the other hand, if he gets a baby girl, she should take 1/3 of the property and 2/3 should go to his wife. Eventually he dies and shortly after, his expectant wife delivers a twin, a baby boy and a baby girl. Unfortunately he didnot leave any instructions for the case of a twin, but however the property must be divided among them, i.e. his wife, his son, and daughter in a fair and square method, befitting in a way that honours his intentions and sentiments while he made out his will. How best could it be accomplished?

Answer:

If you study carefully the problem, you will notice that the deadman's intention was his boy should get twice of what his wife gets and also he wanted that his wife should get twice of what her daughter gets. Hence if we assume that what his daughter gets is 1 unit, then his wife should have 2 units, and then his son, 4 units, totalling 7 units as the whole estate or property. Therefore, the right proportion by which this could be divided is, the daughter's share = 1/7 of whole property, the wife's share = 2/7 of whole property and the son's share is 4/7 of the whole property.
