Question

The ratio of copper to zinc in an alloy is 5:3. If the
weight of the alloy is 84 kg, find the weights of copper and zinc.​

Answer 1

Answer:

On adding the ratio,

5+3=8

therefore,

weight of copper=5/8×84=105/2=52.5kg

similarly, weight of zinc=3/8×84=63/2=31.5kg

Answer 2

Answer:

Copper:52.5kg and Zinc:31.5kg

Step-by-step explanation:

Weight of alloy:84kg

Sum of the ratio: (5+3)=8

Copper: (5/8×84/1)5×21=105÷2=52.5kg

Zinc: (3/8×84/1)3×21=63÷2=31.5kg

Answer:Copper: 52.5kg and Zinc:31.5kg
