BPL accounting ratios?

Can anyone tell me a site where I can get the accounting ratios of BPL, like Working Capital Ratio, Proprietary ratio, etc. The B/S and P/L a/c is available on this site: a href="http://indiaearnings.moneycontrol.com/sub_india/financialreports.php?sc_did=BPL&type=balance" rel="nofollow"http://indiaearnings.moneycontrol.com/su…/a
