$(12$ Tasks to $4$ Workers$)$ Consider the following tasks that must be assigned to four work$-$ ers on a conveyor$-$paced assembly line $($i$.$e$.,$ a machine$-$paced line flow$).$ Each worker must perform at least one task. There is unlimited demand.

Time to Complete Task $($seconds$)$

Task $130$ Task $225$ Task $315$ Task $420$ Task $515$ Task $620$ Task $750$ Task $815$ Task $920$ Task $1025$ Task $1115$ Task $1220$

The current conveyor$-$paced assembly$-$line configuration assigns the workers in the following way:

Worker $1$: Tasks $1,2,3$

Worker $2$: Tasks $4,5,6$

Worker $3$: Tasks $7,8,9$

Worker $4$: Tasks $10,11,12$

What is the capacity of the current line?

What is the direct labor content?
