Simtech Lid. plans to sell $30,000$ units next year. The expected cost of goods sold is as follows:

$\backslash$table$[[$Raw material,Rs$.($Per Unit$)],[$Manufacturing expenses,$100],[$Selling price,$30],[$The pution at various stages,$]]$

The duration at various stages of the operating cycle is expected to be as follows:

Raw material stage

Work$-$in$-$progress stage

Finished stage

$2$ months

$1$ month

Debtors stage

$\frac{1}{2}$ month

$1$ month

Assuming the monthly sales level of $2,500$ units, estimate the gross working capital requirement. Calculate the gross working capital requirement, and work$-$in$-$ progress in $25\%$ complete with respect to manufacturing expenses.
