Question

The ratio of copper to zinc in an alloy is 5 : 3. If the weight of zinc in the alloy is 36.6 g, find the weight of copper in the alloy

Answer 1

Answer:

Given the ratio of copper and zinc in an alloy is 5:3.

Let weight of copper and zinc be 5x and 3x.

Then according to the problem we have,

5x=30.5

or, x=6.1

Then weight of zinc is 3×6.1=18.3 g.
