Answer:

62.5%

Step-by-step explanation:

We are given that

A ten-station transfer machine has ideal cycle time=30 sec=
(30)/(60)=0.5 min

Frequency of line=0.075 stops per cycle

Average time=4 min

We have to determine the line efficiency


T_p=0.5+0.075(4)=0.5+0.3=0.8

Line efficiency=
(0.5)/(0.8)* 100=62.5%

Hence, the line efficiency=62.5%
