BSE: Top gainers and losers

Markets ended flat amid a volatile trading session on Monday led by engineering major Larsen & Toubro after the company reported better-than-expected second quarter numbers last week.

The 30-share Sensex ended up 11 points at 20,894 and the 50-share Nifty closed 16 points higher at 6,205.

The rupee continued to trade weak due to dollar demand by importers.
