Five jobs $(J1, J2, J3, J4$ and $J5)$ need to be processes in a factory. Each job can be assigned to any of the five different machines $(M1, M2, M3, M4$ and $M5)$. The time durations taken (in minutes) by the machines for each of the jobs, are given in the table. However, each job is assigned to a specific machine in such a way that the total processing time is minimum. The total processing time is _____ minutes.

$$\begin{array}{|l|l|l|l|l|l|} \hline \\ {} & M1 & M2 & M3 & M4 & M5 \\ \hline J1 & 40 & 30 & 50 & 50 & 58 \\ \hline J2 & 26 & 38 & 60 & 26 & 38 \\ \hline J3 & 40 & 34 & 28 & 24 & 30 \\ \hline J4 & 28 & 40 & 40 & 32 & 48 \\ \hline J5 & 28 & 32 & 38 & 22 & 44 \\ \hline \end{array}$$
