Alloy

The first alloy is a mixture of two metals in the ratio 1:2, the second is a mixture of same metals in the ratio 2:3. At what ratio we have these two alloys put into the furnace to obtain a new metal alloy with ratio 17:27? (All three ratios correspond to the same order of the two metals).

Correct result:

k =  0.29

Solution:

12k+23=1727(k+1)  k=270.29

1/2•k+2/3=17/27•(k+1)

7k = 2

k = 27 ≈ 0.285714
