How is the amount from the sale of a house divided, which was inherited by four sons, six daughters, and the mother, given that the entire amount was paid for another house?

Each heir owns a share in the new house proportional to what they paid for it. If each heir paid their share of the old house's price towards the new house, then the new house's price is divided among them in the same way the old house's price was divided. To know how to divide the inheritance, the heirs must be clearly identified.
