[quote author=SarahD post=36994954]If you save 2000naira every month at 12% per year, you would have saved 24000 in the first year. Your interest for first year will be 2880naira and your money in will be 24000+2880= 26880. In the second year, you will save an extra 24000, add it to 26880 of last yeat and your principal will be 50880. 12% of 50880 is 6105,6naira, you will now have 50880+6105.6, which gives you 56985.6 naira at the end of the second year. In the third year, your principal will be 56985.6+another 24000 which is 80985.6naira. Then get 12% of that and you continue calculating it in that manner till you get to the 20th year.

benedima1990:It is not even pure compound interest because you have to be adding the savings continuously. Well, the amount to be carried forward to the next year includes the Old Principal+Interest+Savings. It's more of compounding an ''ENFORCED'' principal. 1 Like |

This is pure Economics not Mathematics to calculate just use this formulae. FUTURE WORTH= PRESENT VALUE( 1+ INTEREST RATE ^Number OF YEARS) I.e FV= PV (1 + r^20 ) Fv ? Pv= #2000 r= 12% I.e 0.12 remember it's in % n= 20years Therefore, FV= 2000 (1+ 0.12^20) = 2000 ( 1.12^20) 2000 X 9.646293093 = #19,292.58619 Thank you all I think you are convinced now like if you love ❤ Economics + Mathematics |

Kennedyiheme:The interest alone is 578400 according to my calculation. Don't forget the 480,000 he has deposited already. |
Re: If You Can Solve This Maths, A Financial Institution Should Employ You. by Kennedyiheme: 2:36pm On Aug 16, 2015 |
DesChyko:the question says the man deposits 2000 naira monthly which is 24000, with an annual interest of 12%, meaning the interest fr year one wld be 12% of 24000= 2880, multiply by 20yrs=57600..........if every bank gives there customer 19million as the total interest of the money the deposit tht isn't up to a million, don't you think the bank will rundown? Logically its impossible for a bank to give u 19million because u deposited 480,000 |
