There are three stations in a process: Station$-1,$ Station$-2,$ and Station$-3.$ Three products are produced in this process: Product$-$A$,$ Product$-$B$,$ and Product$-$C$.$

The total volume of production is $103$ products per hour. Product$-$A is produced at a rate of $26$ units per hour. Product$-$B is produced at a rate of $33$ units per hour. The rest of the production is Product$-$C$.$

Product$-$A goes through Station$-1$ and Station$-2.$ Product$-$B goes through Station$-1$ and Station$-3.$ Product$-$C goes through all three stations.

On average, there are $34$ units of different products in Station$-1,49$ units of different products in Station$-2,$ and $51$ units of different products in Station$-3.$
