It is desired to produce a copper–nickel
alloy that has a minimum noncold-worked
tensile strength of 350 MPa (50,750 psi) and
a ductility of at least 48%EL. Is such an
alloy possible? If so, what must be its composition?
If this is not possible, then explain
why.
This is question #24, Chapter 10 in the Fundamentals of Materials Science 5ed from Callister.
A similar question in also asked on the 3e of "Fundamentals of Materials Science: an introduction" by Callister and Rethwisch, question #15, also chapter 10.

I don't have the book, but there should be a graph with Ni% or Cu% on the x-axis and either Ultimate Tensile Strength or Ductility on the y axis. It should be a curve. Find the composition you need to get the UTS and then see if that ductility is possible for that composition.
Hope that helps.
