I wish to visit nigeria, I love nigeria.

Thermodynamic:
SOUTH AFRICA!!

Yes My brother; south africa is the best country in africa/ the world.

Lilyomi:
Wen wl it b other african countries o. Hmmm

Fix your cities first, there after advertise your countries to the world,and stop running to other countries, then your dream will come true. Durban is one of the beautiful city in south africa, you can't compare durban with any other city in africa except one city from north africa region.

This is south africa rural roads, road markings are very important to avoid accidents.

[quote author=ckenneths post=37240084]You would not believe that this is a part of Nigeria. This is a village in the center of nowhere, but the roads here are so clean, so paved that you would think you are in the US.

The class room looks dirty, the wall paint isn't good, the floor it has potholes , the chairs aren't on a good standard for learning, that is why they are sleeping. That's my opinion.

I sarcastically called you a 'mathematician'. You are absolutely wrong!

It does't matter, but I know my answer is correct.

itopicman:
This solution is very wrong. You've simply accumulated the total savings and computed a single interest on it at the end of the 20 years period using
Amount = P(total) + [P(total)xRate/100]. The given rate(R) is annual and not for 20 years. This is wrong sir!

Check my solution pls.
This is a complex form of a Compound Interest question. (Reason: You need to keep on adding the monthly savings he makes per month.)
The mistake from many is to assume a one-time principal.
For clarity, at the end of the first year, the Principal = #2000 x 12 = #24000. 12% interest on this gives 24000 x 0.12 = 2880.
At the end of the 2nd year, the New Principal = (Principal of year 1) + (Savings/principal of year 2) + Interest from year 1 = 24000 +24000 +2880 = 50880. Interest from year 2 = 50880 x 0.12 = 6105.6. At the end of year 3, the New Principal = (year 1 principal) + (year 2 principal) + (year 3 principal) + (Interest from year 2) = 24000 + 24000 + 24000 + 6105.6 = 78105.6. and on and on like that.
As a mathematics student, I computed an analytical equation for this 'progressive compound interest' problem thus.

Amt=yp*(n+(n*x)+((n-1)*x^2)+((n-2)*x^3)+((n-3)*x^4)+((n-4)*x^5)+((n-5)*x^6)+((n-6)*x^7)+((n-7)*x^cool+((n-cool*x^9)+((n-9)*x^10)+((n-10)*x^11)+((n-11)*x^12)+((n-12)*x^13)+((n-13)*x^14)+((n-14)*x^15)+((n-15)*x^16)+((n-16)*x^17)+((n-17)*x^18)+((n-18)*x^19)+(x^20))
yp = yearly savings/principal = #24000,
n = number of years = 20,
x = interest rate per annum = 12% = 0.12,
Amt = Amount at the end of 20 years
Amt = # 545,010.

I don't understand why you add the interest of the first year on second year.

Total savings on 1rst year=24000
& total interest is: 24000*0,12=2880
Total amount p/a:
total savings+total interest
24000+2880
26880

For second year is:
Total savings+total interest
Total savings=2000*24=48000
Total interest=48000*0,12=5760
.:total amount for 2nd year is:
=48000+5760
=53760

the total amount of 20 year is:
Total savings+total interest
Total savings=2000*12*20=480000
Total interest=480000*0.12=57600
.:total amount+total interest
480000+57600
537600
Don't apply arithmatic formula to get the answer, because interest rates are different.

Mathematician!

I enjoy to solve difficult problems, thanks for your support.

walexy30:
I save N2000 every month in a bank with an annual interest rate of 12% for 20 years while still working. How much will i receive at the end of the period (20 years).

The correct answer is:
20 years total savings*interest rate
(2000*12*20)(1+12/100)
(480000)(1,12)
537600

The question is simple

mozeybee:
Hun. Thank you sir/ma. This is a really detailed solution.

No! Don't thank him; His answer is incorrect

kelly8919:
The ans is A which is 18. Solution: 3+3*3-3+3 . 3+3*3 . 6*3 . =18

Corrections:3+3*3-3+3
3+3*3
3+9. Multiply first(Bodmas)
12

anyicash:
The ansa is 6...just apply BODMAS

You apply your bodmas the wrong way. You need help.

-3+3=0 and +3-3=0
Use Calculator to prove this.

-(3+3)=-3-3 not -3+3=0
-(3+3)=-6. Not -3+3=0
Wrong. Correct

timota:
BODMAS. 3+(3x3) -(3+3)=3+9-6=12-6=6

Corrections: -3+3 not = to -(3+3)
Let us check -(3+3)=-3-3 if you multiply the braket of 3+3 by negative.
So -3+3 must remain the same=0

3+3*3-3+3
Or you can apply bodmas rule to get the correct answer

3+9-3+3 multiply 3*3 first. (3+9)=12 and (-3+3)=0
Therefore
12+0=12

Nomswilli:
wake me up from a deep sleep
3+3*3-3+3,

3+(3*3)-(3+3),

3+9-3-3,

3+9-6,

12-6=6
d ansa remains d same

Let me wake you up!
The quetion is
3+3*3-3+3
3+3*3+(-3+3) you can't put - out of () and left the other 3 positive,if you put - out () you suppose to have this:
3+3*3-(3-3)
3+9-(0)
12

I GAVE HIM A FREE LECTURE ON THE HISTORY OF OUR UNIVERSITIES. Some classes ae available in UCT FREE OF CHARGE.

Back to the topic, all S.A. top universities were built from GOLD AND DIAMOND MINING MONEY. Its a known fact even during the "RHODES MUST FALL CAMPAIGN" white stuents like WHITE PREVELAGE ASSOC. lectured other white kids on how they got their status today and how varsities like UCT were built. Again if u visit the UCT library HISTORY section u will see it all and see that black labour built UCT and many S.A varsities.

From 1st thread...by OP he gave u history but u chose to be an OKONKWO like many Igbos.
1. UNIVERSITY OF CAPE TOWN



Established 1st October 1829, optimism is the official creed of this university, which has the motto “Spes Bona” (“Good Hope”). The University of Cape Town has consistently ranked at the top of best universities in Africa. The University of Cape Town started off as a College with a small tertiary-education facility that grew substantially after 1880, when the discovery of gold and diamonds in the north – and the resulting demand for skills in mining – gave it the financial boost it needed to grow. The College developed into a fully fledged university during the period 1880 to 1900.

As far as I know them, they will never understand anything, Beside the rubish coming out of their "hammer heads"
