Question

The ratio of copper and zinc in an alloy is 5:7. if the weight of copper is 35.5 kg, what is the weight of zinc.

Answer 1

Answer:

The weight of zinc will be 49.7 kg

Step-by-step explanation:

Let the weight of copper be 5x and zinc be 7x.

Then according to the question 5x=35.5 which implies x=7.1 .

Thus 7x=49.7

Hence the weight of zinc will be 49.7 kg
