Question

In an alloy the ratio of zinc aluminium and copper is 8: 7 :6 if the weight of zinc 32 kg find the weight of aluminium and copper i n
the Alloy

Answer 1

let the mass of zinc=8x
mass of aluminium=7x
mass of copper=6x

mass of zinc=32kg
so 8x=32kg
so x=4
so mass of aluminium =7x=28kg
mass of copper=6x=24kg

Answer 2

let the weight of zinc be 8x

and weight of aluminum be 7x

and weight of copper be 6x

now weight of zinc is 32 kg

1. 8x =32kg
2. x=4kg.

therefore, weight of aluminum is = 7x=7×4=28kg

weight of copper =6x =6×4=24 kg
