Answer 1

Given:

The ratio of copper and zinc in an alloy is 5:7. if the alloy contains 35.5 gram of copper, how many gram of zinc does it contain?

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
