Question

i

The ratio of brass and copper in an alloy is 3 : 5. If the weight of copper is 3.2 kg, find
the weight of brass in the alloy.
​

Answer 1

Answer:

1.92 Kg

Step-by-step explanation:

A alloy is a metal made by mixing two types of metal together.

In this question the alloy is made up of brass and copper  

Ratio = brass : copper = 3 : 5

brass = 3x and copper = 5x

given copper = 3.2 Kg

5x (copper) = 3.2 Kg

x = 3.2 / 5

x = 0.64

brass = 3x = 3(0.64) = 1.92 Kg
