Question

The ratio of copper and zinc in an alloy is 9:7. If the wright of zinc in the alloy is 9.8 kg, find the weight of copper in the alloy​

Answer 1

Answer:

12600

Step-by-step explanation:

sum of ratio 9+7=16

let the total weight of alloy be x

ratio of zinc =7

7/16 ×x=9800gram

x = 9800×16/7

x = 1400×16

x = 22400

weight of copper = 9/16×22400= 12600
