Answer:
The weight of copper in alloy is 14 kg.
Step-by-step explanation:
Weight of alloy = 24 kg
Ratio of zinc and copper = 5:7
Weight of zinc = 5x
Weight of copper = 7x
So,
=> 5x + 7x = 24
=> 12x = 24
=> x = 24/12
=> x = 2
Therefore,
Weight of copper = 7x = 7*2 = 14 kg
Weight of zinc = 5x = 5*2 = 10 kg
