2)what principal will amount to rupees 13680 in 1 year and 9 months at 8%p.a.? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 1)250 x 7=1750 cost for cones
240/2 x 17=2040
2040-1750/250=1.16, or 16% profit per cone
2) 13680=n*(1+0.08)^1-9/12
13680=n*(1.08)^1.75
ln 13680=ln n + ln(1.08)^1.75=ln n + 1.75 ln 1.08
ln n=9.3890083691883168863468258972402
n=e^9.3890083691883168863468258972402=11,956.23 rupees to start with
