The ratio of copper and zinc in an alloy is 9:8. If the weight of zinc in the alloy is 9.6 kg find the weight of copper in the alloy

Let the weight of copper = x kg

Weight of zinc = 9.6 kg.

According to question,

Ratio= 9 : 8 = x : 9.6
Product of means = Product of extremes

=> 8 x x = 9 x 9.6
=> x = (9 × 9.6)/8 = 9 x 1.2 = 10.8 kg.
Weight of cooper in alloy = 10.8
