A friend text me this info and from my own little survey, it's most probably correct.

1. Crude Oil daily production - 2.5m barrels
2. Current crude oil price - $113/barrel
3. Daily Sales - 2.5m x $113 = $282.5m
4. Monthly Sales - $282.5m x 30days = $8.475billion
5. Yearly Sales - $8.475m x 12 = $101.7billion
6. Naira equivalent - $101.7billion x 160 = N16.272trillion/year
7. Nigeria's 2012 budget - N4.5trillion
8. Above budget - N16.272trillion - N4.5trillion = N11.772trillion

Now the question is; where is the N11.772trillion going.
