Question

in an alloy of German Silver the ratio of copper to zinc was 17 :7 while that of nickel to zinc was 4:3 .the ratio of copper to zinc to Nickel in the alloy was?

Answer 1

Ratio : Copper : Zinc = 17 : 7 (Given)

Multiply the ratio by 3 :

Ratio : Copper : Zinc = 51 : 21

Rato : Nickel : Zinc = 5 : 3 (Given)

Multiply the ratio by 7:

Rato : Nickel : Zinc = 35 : 21

Find the ratio of Copper to Zinc : Nickel

Ratio Copper : Zinc = 51 : 21 : 35

Answer: The ratio is 51 : 21 : 35
