Question

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.

Answer 1

Step-by-step explanation:

• ratio of copper and zinc in an alloy is 9 : 8

• weight of zinc = 9.6 kgs = 9600 grams

8x = 9600 grams

x = 1200 grams

wt. of copper = 9x = 9 * 1200 = 10800 grams

= 10.8 kgs of copper
