"But when we interpret in the distance format, the sequence flips i.e. the distance between final mixture and A will be 3 units and that of between final mixture and B will be 4 units.Now to calculate the compostion of the first metal in X, add the 4 units to 1/3.i.e. \\(4/7 *\\)\\(7/24\\) \\(+1/3\\) ORsubtract 3 units from 5/8 i.e. \\(5/8 -\\) \\(4/7\\)\\(* 7/24\\).This will come out as 50%.Therefore the othe" .
