There are two equations here, either of which, when solved, will give the correct answer.
1)\((\frac{3}{7})*X+(\frac{5}{7})*Y = (\frac{1}{2})*(X+Y)\)
2)\((\frac{4}{7})*X+(\frac{2}{7})*Y = (\frac{1}{2})*(X+Y)\)
A common mistake is to take RHS as (X+Y) instead of\((\frac{1}{2})*(X+Y)\)
The ratio\(\frac{x}{y} = \frac{3}{1}\)
