a family consists of 6 members p, q, r, x, y, z. q is the son of r but r is not mother of q. p and r are married couple. y is the brother of r, x is the daughter of p. z is the brother of p. how many female members are there in the family?

Answer: Let’s analyze the information given:

  1. p and r are married couple: This implies that p and r are a husband and wife.
  2. q is the son of r but r is not the mother of q: This implies that r is the father of q. Since q is not r’s son, r must have married someone else before marrying p.
  3. y is the brother of r: This indicates that y and r are siblings.
  4. x is the daughter of p: This means that x is the child of p and r.
  5. z is the brother of p: This means that z and p are siblings.

Based on this information, we can construct the family tree as follows:

   p ---- r
  / \      \
 z   x      y
           /
          q

From the family tree, we can see that there are 2 female members: p and x.
