Mumbai, April 22: The Rupee on Thursday tumbled down 21 paise to 75.08 against the US Dollar in opening trade on rising demand for US Dollar by bankers and importers, dealers at the Forex Market said.

The domestic unit was seen as weak because of the firm dollar against other world currencies amid a negative stock market in early trade.

The Rupee registered days high and low at 75.12 and 75.01 respectively. (UNI)
