$7($c$)$

$($c$)$ A computer assembly line requires the following tasks to be performed in the given sequence $($Figure $4).$ Task durations are given in seconds. The factory has an annual demand of $3750$ computers per week. The factory operates one shift $(7$ hours$)$ per day, five days a week. Find the minimum number of workstations necessary to run this assembly line and assign tasks to these workstations. Multiple tasks can be assigned to a workstation as long as there is no bottleneck. You cannot violate the precedence of tasks for any workstation $($i$.$e$.,$ task $"$C$"$ cannot be assigned without assigning task $"$B$"$ to a workstation first$).$ Calculate the average efficiency of the assembly line.
