Explain the central problem of production with the help of production possibility curve?

For the problem how to produce, if economy operates within the PPc resouces are underutilised. So economy will choose those techniques(capital or labour intensive) which makes the economy ooerate on a point on the PPC curve.for what to produce, the economy gets various nethods of production at different poing on the PPC like point A, B , C etcfor whom to produce assume two goods as luxury good and necessity good. And the more the PPC is incloned to one good among these solves the problem of for whom to produce ie. Rich or poor :)
