The deceased is survived by his mother, 2 sons, 2 daughters and one brother.

Answer

Mother one sixth. The balance will be divided into 6 shares. Each son receives two and each daughter one share. Alternately, divide the estate into 36 shares and distribute as follows: Mother 6, each son 10 and each daughter 5. It has been assumed that the deceased was not survived by any of his parents. The brother does not inherit.
