Calculate working capital from the following information-

₹450000

Working capital = current asset - current liabilities
                       = 600000 - 150000
                       = ₹450000

*Current liabilities = Trade payables + Provision for tax
                          = 140000 + 10000
                          = ₹150000

*Current assets= Inventory + trade receivables + marketable securities + cash and bank balance
                     = 360000 + 170000 +50000 + 20000
                      = ₹600000
