Cbn sells 210m as naira closes at 363 dollar #
It looks like you're trying to calculate the value of the Central Bank of Nigeria (CBN) selling 210 million dollars at the current exchange rate of 363 naira per dollar.
To do this, you can multiply the number of dollars sold by the exchange rate:
210,000,000 dollars x 363 naira/dollar = 76,530,000,000 naira
So, the CBN would sell 210 million dollars for approximately 76.53 billion naira.
