October 2015 Problem

A rich merchant left a testament: If my wife delivers a boy, after my death she receives 1/4 of my property and my son - 3/4. If this is a girl, my wife receives 3/4 and my daughter - 1/4. A week after the merchant passed away, his wife delivered twins - a boy and a girl. How will you share the heritage between them, respecting the merchant's will?

Dear visitors, thank you for your solutions. Many of them were interesting, but sadly incorrect. Here is my solution: In both cases the pattern is that the mother receives 3 times less than her son and three times bigger than her daughter. Thus, we have 13 shares - 1 daughter's, 3 mother's and 9 son's. Thus, the girl should receive 1/13 of the capital, her mother 3/13 and the boy - 9/13. Respectfully, Serge Hazanov
