Account receivable turnover in days and inventory turnover in days are negatively related with profitability and both are also significant. Account payable is also negatively related but not significant .but in the given data cash conversion cycle cannot be proved negatively related with the profitability and it is also insignificant, as most of the analysis indicate that proxies are linked with profitability of the organization.
