How is the estate of a man who died leaving a wife, a mother, four sons, and two daughters to be distributed?

There are fifteen male heirs and ten female heirs. The division of the inheritance cannot be determined until the heirs are enumerated. If we assume that the deceased left no heirs other than his mother, his wife, his two daughters, and his four sons, then the mother receives one-sixth due to the presence of a lineal descendant, and the wife receives one-eighth due to the presence of a lineal descendant. The remainder goes to the sons and daughters by ta'sib (residuary heirship), with the male receiving the equivalent of the share of two females. The inheritance is divided into 240 shares: the mother receives 40 shares, the wife receives 30 shares, each son receives 34 shares, and each daughter receives 17 shares.
