  • Question
  • 4 kg of a metal contains 1/5 copper and rest in Zinc. Another 5 kg of metal contains 1/6 copper and rest in Zinc.The ratio of Copper and Zinc into the mixture of these two metals:


  • Options
  • A. 49 : 221
  • B. 39:231
  • C. 94:181
  • D. None of these

  • Correct Answer
  • 49 : 221 

    Explanation

    Copper in 4 kg = 4/5 kg          and      Zinc in 4 kg = 4 x (4/5) kg

     

    Copper in 5 kg = 5/6 kg          and      Zinc in 5 kg = 5 x (5/6) kg

     

    Therefore, Copper in mixture =  4 5 + 5 6 = 49 30  kg

     

    and  Zinc in the mixture = 16 5 + 25 6 = 221 30 kg

     

    Therefore the required ratio = 49 : 221
