the Terminal Company Is Attempting to Balance Its Assembly

Table 10.23
The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors. The desired output for the line is 50 connectors per hour, and the information on the work elements for this assembly line is as follows.
$$\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Work } \\\text { Elements }\end{array} & \begin{array} { c } \text { Time } \\( \mathrm { sec } ) \end{array} & \begin{array} { c } \text { Immediate } \\\text { Predecessor(s) }\end{array} \\\hline \text { A } & 40 & - \cdot \\\text { B } & 36 & \text { A } \\\text { C } & 20 & \text { A } \\\text { D } & 2 & \text { A } \\\text { E } & 30 & \text { B, C } \\\text { F } & 34 & \text { D } \\\text { G } & 35 & \text { E } \\\text { H } & 5 & \text { F } \\\text { I } & 15 & \text { E, H } \\\text { J } & 40 & \text { H } \\\text { K } & 38 & \text { G, I, J } \\\hline\end{array}$$
-Use the information from Table 10.23, and the longest work- element rule to balance this line. What is the efficiency of the solution?

A) more than 90%
B) 80- 90%
C) 70- 79%
D) less than 70%
