Q$5.$ Suppose that four machines, $1,2,3,$ and $4$ have been identified as belonging in a GT machine cell. An analysis of

$50$ parts processed on these machines has been summarized in the From$-$To chart presented below. Additional

information is that $50$ parts enter the machine grouping at machine $3,20$ parts leave after processing at machine $1,$

and $30$ parts leave after machine $4.$ Determine a logical machine arrangement using Hollier method.

Compute the $($a$)$ the percentage of in$-$sequence moves $($b$)$ the percentage of by$-$passing moves $($c$)$ the

percentage of backtracking moves
