Good morning to you all...this question giving moi a blip...rescue me palz:


4. A man owns 2/3 of the market research bureau businness and sells 3/4 of his shares for $75000. The value of the business is: a. $150000 b. 130000 c. $240000 d. $340000 e. None

2/3 of B=S(the man's shares)...........I
3/4 of S = $75,000................II
S = $75,000 x 4/3 = $100,000
Recall that B (value of business) = 3/2 of Shares (when u make B the sub. Of formula in I)
B =3/2 x$100,000 = $150,000. A!

thanks alot for ur assistance, my elder brother has been advising me to study Welding and Fabrication Engineering Technology at PTI just because he said there will be alot of job offer but I dont like the course, secondly I thought Petroleum Engineering is a bit diff and was pointing Petroleum and Gas Processing Engineering to be Chemical Engineering cos that how it is on the form.

Well it all depends on what u want sha...4 me they're all good courses.

Thanks.

ade2291:
thanks boss, what about the one with the most success, i mean the Job offer aspect. I am not like those who only want to work in oil and gas company, I do n't care about that, I hope I can work anywhere with any of this certificate?

I think petroleum is richer but opportunities are limited while going for a proffesional training in, say, Autocad or any other IT field after school will give u an edge in job-seeking for Mech Eng.

opeaceo:
Yes, it won't be harmful, I think the North would benefit a lot more if we utilize it than any other part of the country.

Yeah...they've also got wind over there

ade2291:
pls which is easier to study between Petroleum and Gas Processing Engineering and Mechanical Engineering Technology?? pls help cos i don't want to end up regreting my decision...

No engineering course is more easier to study than the other it all depends on ur passion. If u love mech eng. No matter how tough it is, u'd still keep pressing on. So discover the one u have passion 4 most.

Princecalm:
hmmm, are you sure about that figure?

Yeah.
We can take the arguement here:

opeaceo:
The gases being flared in the South should be stopped and put to good use and more hydro power plants should be built.
You mentioned solar power, solar power isn't that reliable. I would have suggested Nuclear power and Fossil fuels, but Nigeria as a country cannot handle the hazards that comes with it.

Good one, but we have abundance of sunshine over here...it won't be harmful if we utilize that. U know it doesn't have any effect on the environment.

Here's a biscuit to add to the tea...

Rambos! Take this morning tea!
If (2/4)^x (2/3)^y = 32, find the value of 3y - 2x

A. -1
B. 7
C. 1
D. -7
E. What you think it is....(In case)

In your own thoughts, what do you think is the solution to the power crisis in Nigeria? Remember many companies have relocated to other neighbouring countries because, there's no electricity power in Nigeria. Also remember the story of the guy who lost a job interview because he didn't have 'light' to iron his clothes. So how do we solve this?

I'm of the opinion that each household should raise enough fund to become solar powered thereby reducing the dependence on the Government to provide energy.

If na Tonto Dike snap picture with her dogs, we for don get like 6 pages of comments. Smh

I believe putting all these in mind would make one focused and not follow after irrelevances. Nice!

Seun we need more smileys pls...

Dey dream dey go

Did the man also create engine to work with that fuel? Cos an engine designed for petrol can work for another

I dunno...but I think he's capable of dat to; he's a professor.

Princecalm:
the question is how many average Nigerians can afford that amount because that is approximately 48000000 naira at 160 conversion rate

Lol...I was referring to ur figure in Naira...don't mind d dollar sign

Ok now...here's a fact.
The cost of a full solar electric system is about $10,000. i.e it would cost an household that amount to be powered.
And we have abundance of sunshine!

Zedric:
Dude, did you really just call $300,000 meagre? Or you meant #300,000? Btw, #300k will never be enough for solar power

I believe one day naira would equal dollar
BtW, just as we make provisions to build houses, we should also make provisions for Power...I heard of a lecturer in Lasu who makes his own fuel from bio materials....

Morning Gracie...I've been looking all-over 4 you.

Princecalm:
then up to 50,000 will be writing pume.

Damn!

dharay88:
na love cus am.

Ta! Iffa hear....if she no uppload her pics, he go fall in lust?

Princecalm:
morning bro,but that will be meant for individuals who can afford the cost, and I bet you don't know how much. For even an electrical rechargeable inverter ranges from #150000(5kva) to 250000(10kva)

Just a meager $300,000 at most...and u're free from power hassle 4 life? Bro! Look at it na...if we calculate how much we don dey pay for Nepa bill, e don reach to buy 2 inverters na

But imagine if uniben now releases 180 as their cut-off mark this year?
