23 : 11

Let x be the total population of all the seven villages.
Population of village T below poverty line
          equals space space straight x space cross times space 21 over 100 space cross times space 46 over 100
Population of village Z below poverty line
            equals space straight x space cross times space 11 over 100 space cross times space 42 over 100
∴  Required ratio:
