MR. jhon is offered an annuity plan for $250000 that will provide him $30000 annually at start of each year @8% p.a how long it will take him to get return?
"PV =\\$250000"
"r=8%" %
"i=0.08"
"R=30000"
"250,000=30000[\\frac{(1+0.08)^{-n}}{0.008}]"
"\\frac{250,000\\times0.08}{30,000}=1-(1+1.008)^{-n}"
"0.67=1-1.008^{-n}"
"1.008^{-n}=0.33"
"-n=\\frac{log \\ 0.33}{log\\ 1.08}"
"-n=-14.41\\\\\nn=14.41"
"n=14.4"
