This method is adapted to reckoning intereft at the rate of 
6 per cent.— But from the intereft at 6 per cent. the intereft at 
any other given rate may be obtained, as follows : 
One fixth part of the intereft at 6 per cent. is the intereft at 
1 per cent.—One third is the intereft at 2 per cent.—One 4a/f 
is the intereft at 3 per cent. If from the intereft at 6 per cent. 
there be fubtracted one zhird of it, the remainder will be the 
‘intereft at 4 per cent.—If one fxth be fubtracted, the remain- 
der will be the intereft at 5 per cent. | 
Again.—If to the intereft at 6 per cent. there be added one 
fixth part thereof, the fum will be the intereft at 7 per cent.— 
If there be added one zZ/r4, the fum will be the intereft at 8 
per cent.—If there be added half, the fam will be the intereft. 
at 9 per cent. —If two thirds, the fum will be the intereft at 
1o per cent.—If one a] If and one third, the fum will be the 
intereít at 11 peek double of the intereft at 6 per 
cent.
