Why Electrosteel quoting 10 times at BSE as compared to NSE

Stock is listed at 31 at BSE and 2.60 at NSE.

Face value is same (Rs.10) and ISIN number is also same. Verified from both exchanges.

Any idea why this difference in price.

Note: I am aware of Vedanta's exit plan for Electrosteel shareholders but this still not explain the massive difference in share price at 2 exchanges.
