Mumbai: The rupee on Tuesday rose marginally by one paisa to 83.36 in the opening session against US dollars on the sale of US dollars by bankers and exporters, dealers at the Foreign Exchange said.

The local unit improved due to a weak dollar against other world currencies amid a strong opening in the equity market.

The rupee recorded intraday highs and lows at 83.34 and 83.37, respectively, the dealer added.
