If u mean
4kg of a metal contains 1/5 'parts of ' copper and rest is zinc.another 5kg of metal contains 1/6 'parts of 'of copper and rest is zinc.

Then amt of copper in 4 kg mixture = 4/5 kg.
Then amt of zinc in 4 kg mixture = 16/5 kg
Then amt of copper in 5 kg mixture = 5/6 kg
Then amt of zinc in 5 kg mixture = 25/6 kg

Ratio of copper to zinc in final mixture = (4/5 +5/6) : (16/5+25/6)
= 49/30 : 221/30 = 49:221
