The ratio of zinc and copper in an alloy is seven ratio nine if weight of copper in the alloy is eleven point kg then find the weight of zinc in the alloy
7/9 = z/11
Cross multiply to solve for z.
Copper=c
Zinc=z
APQ (As Per Question)
C:Z=9:7
11.7/Z=9/7
Z=9*10/117*9
Z=9.1kg
To find the weight of zinc in the alloy, we need to use the ratio provided and the weight of copper given.
Given:
Ratio of zinc to copper = 7:9
Weight of copper = 11.0 kg
First, let's calculate the total weight of the alloy using the weight of copper:
Total weight of alloy = Weight of copper / Ratio of copper in the alloy = 11.0 kg / 9
Next, we need to find the weight of zinc using the ratio of zinc to copper:
Weight of zinc = Total weight of alloy * Ratio of zinc in the alloy = Total weight of alloy * (7/9)
Substituting the value of the total weight of the alloy, we have:
Weight of zinc = (11.0 kg / 9) * (7/9)
Now, let's calculate the weight of zinc in the alloy:
Weight of zinc ≈ (11.0 kg / 9) * (7/9) ≈ 7.358 kg
Therefore, the weight of zinc in the alloy is approximately 7.358 kg.
