Your answer is in the question; that is, if you have transcribed the question correctly.

Explanation:

#PbI_2(s) rightleftharpoons Pb^(2+) + 2I^-#

You have been quoted the concentration of plumbic ions, #Pb^(2+)#. It is easy to see why this concentration is equal to the required solubility. As a followup to this question, what do you think the examiner means by "saturated solution"?
