How is the amount of 54,0 Saudi Riyals divided among heirs consisting of: a mother, a wife, 3 sons, and 4 daughters?

The estate of the deceased, survived by a mother, a wife, three sons, and four daughters, is to be divided as follows: The mother receives one-sixth due to the presence of lineal descendants, and the wife receives one-eighth due to the presence of lineal descendants. The remainder is to be divided among the sons and daughters by ta'sib (residuary inheritance), with the male receiving the share of two females. The estate is divided into 240 shares: The wife receives 30 shares, the mother receives 40 shares, each daughter receives 17 shares, and each son receives 34 shares. The share of each heir is calculated by multiplying the total amount divided by 240 by the number of shares for each heir. Inheritance matters should be presented to Sharia courts, as there may be complexities that only emerge through research and investigation, such as the presence of a missing heir, wills, or debts that take precedence over the rights of the heirs.
