Machines \(X\) and \(Y\) can work at their respective constant rates to manufacture a certain production unit. If both are working alone, then the time taken by machine \(Y\) is what percentage more/less than that of machine \(X?\)
(1) Machines \(X\) and \(Y,\) working together, complete a production order of the same size in two-thirds the time that machine \(Y,\) working alone, does.
(2) Machine \(Y,\) working alone, fills a production order of twice the size in \(6\) hrs.
