The ratio of zinc to copper in some alloy is 2 to 5. If 60 kilograms of zinc are used, how many kilograms of copper are needed to make this alloy

Respuesta :

Answer:

The correct answer is 150 kilograms.

Explanation:

Based on the given information, the ratio of zinc and copper within the alloy is 2:5. The amount of zinc used in the alloy is 60 kg. Now the amount of copper used within the alloy would be,

Zinc/Copper = 2/5

60/Copper = 2/5

Copper(Cu) = 60*5/2

Cu = 150 Kilograms.

Thus, the amount of Cu used in the alloy is 150 Kg.
