The rupee today strengthened by another 12 paise to end at 46.83/84 against the US dollar on sustained selling of the US currency by exporters and banks, amid firm equity markets.
The rupee resumed lower at 47.03/04 per dollar, but recovered immediately to quote 21 paise higher at 46.74/76 in early trade. Later in the day, moving in line with equity markets, it pared some of the gains before closing 12 paise higher at 46.83/84 per dollar.
