Question

The Ratio of copper and zinc in an alloy is 9:8.if the weight of zinc in a alloy is 9.6kg,find the weight of copper in the alloy​

Answer 1

ratio of weight of copper and zinc=9:8

let zinc be 8c and copper be 9c

Given weight of zinc in alloy=9.6kg

ATQ

8c=9.6

c=1.2

weight of copper=9c=9*1.2=10.8kg

Answer 2

Answer:

ratio is 9:8

let weight of copper is 9x

and weight of zinc is 8x

ATQ, 8x=9.6

x=1.2

then weight of copper= 1.2×9=10.8kg
