Metal alloy

What is the ratio of metals in the alloy that is in the 50 tonnes of steel to 30 kg nickel?

Correct answer:

x =  0.06 %
y =  99.94 %
p =  0.0006004

Step-by-step explanation:


x = 100-y
x = 30/(50•1000)•100
p = 30/(50•1000-30)

x+y = 100
x = 0.06
p = 0.0006

p = 3/4997 ≈ 0.0006
x = 3/50 = 0.06
y = 4997/50 = 99.94

Our linear equations calculator calculates it.
p=m(Ni)m(Fe)=3050100030=34997=0.0006004
