Balance the assembly line shown below for (a) a shift output of 60 pieces and (b) a shift output of 48 pieces. Assume an 8-hour shift, and use the rule: choose the assignable task with the longest processing time. Compute the line efficiency for each case.

1. Fill in the table below for a shift output of 60 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number.

   Workstation	Tasks	Total Time	Idle Time
   1	select: ab, ad, cf
   2	select: bceg, bad, degh
   3	select: fi, egh, cfi
   4	select: hkj, ijk, jk
   	Total

   What is the assembly-line efficiency? Round your answer to one decimal place.
