P$1.$ In a production line, the hourly production rate is $600$ parts, In a $8$ hour$-$shift, $30$ min meal break, $10$ min $2$ times tea break, and $2$ times $15$min setup times are recorded as planned activities. Unfortunately, $25$ min failure occurs in the shift with $15$ min lateness for supplying sub material. At the end of the day $2400$ parts are produced and $400$ of them are marked as under quality.
