Doubt in calculating Mutual Fund Dividends?

I have 1000 units of Reliance Diversified Power Sector MF. Current NAV is Rs.50 . On 17-Aug-2007, this MF has declared a Dividend of 30%. Will the Dividend be calculated on the Face Value of the MF (which is Rs 10) or on the Latest NAV of the MF (which is Rs 50) ? In other words, will I get 30% of 10000 or 30% of 50000 as dividend ? Please advice.
