My car is Pontiac vibe 2005 model, I noted that if am on motion be it 40 or 100 and i want to slow down and or stop, as i match my brake pedal my steering will vibrate. I took it to mechanic he said is brake rotors ie brake disc, i bought new one with new original brake pads and fixed still iit still vibrate. I took it back again he check my shocks and charge my both linkage still same thing. Now he asked me to change my brake caliber am afraid to do so. Please friends kindly help me with solutions to fixed it. Godbless you all.

Do you feel pulse from the brake pedal? Does the car have disc or drums in the rear?

Of all answers I've read, you are closest. What folks may not realize is that questions like these are testing your verbal reasoning and not mathematical skills, that's the first thing to know.

1.) It's basic English, they just want to throw you off balance by the statement that the glove is 100times the cost the cup. The statement says they are both N110 which simply means the cost of each of them is N110.

2.) The machines are working independently of each other and as such, they produced one doughnut each at the given time which invariably means the given time is also what it will take for the 100 machines and that is 10minutes.

3) This one took me time to figure out. The answer is that it is only possible by 'his calculation' and not anybody's so, doing mathematical calculations for how he will become a millionaire is a waste of your time. Come to think of it, the category of monetary riches that can make one a millionaire is a very broad range and we are not given any hint that the man wants to be a millionaire in tens or in hundreds. Therefore, only him knows the amount he's targeting to make as profit in millions which makes any calculation aside his own a waste of time

2 is settled leaving us with 1 and 3.

1. A glove and cup both cost 110naira. The cost of the glove is 100times more than that of the cup. How much is the cup?

By English, the first statement is ambigious.
1st meaning: glove and cup all cost inclusive in N110

2nd meaning: glove and cup both cost the same. If this is the case what would be the importance of writing the second statement at all since it counters it.

3. Even by 'his calculation', it is impossible for him to hit 6 zeros. The only answer to this is that any amount less than a billion can be expressed in fractions of a million, so he is a millionaire by expression of a small fraction of a million.

With the Mercury Inverter 2.4kva (24 volt)http://www.mercurydirect.com.ng/mercury-inverter-2-4-kva-user-manual/, the two Mercury Tubular 220amp beauties need to be connected in series to generate the required 24 volts. Since connecting two batteries in series will double the voltage but keep the amperage rating the same, his battery bank will be 220amp. 220Ah÷20A=11hrs
60A charger 220/60 = 3.6hrs
80A charge 2.7hrs
With the Mercury Inverter 1.2kva (12 volt), the two Mercury Tubular 220amp beauties need to be connected in Parallel, because only 12 volts is required. Since connecting two batteries in Parallel will double the amperage rating but keep the voltage same, the battery bank will be 440amp.
440Ah÷20A=11hrs
60A charger 440/60 = 7.3hrs
80A charger 5.5hrs

Thanks for this. There is one little mathematical error as 440 divide by 20 is 22hrs. I believe you have more practical experience than me so i want to ask a practical question after believing this calculations are correct.

Senerio 1 Lets take the set up in concern as consideration. 2 x 220Ah in series with a 2.4Kva 24v inverter and a 20A charger.

The battery bank gives 24vdc and 220Ah. 220÷20=11hrs

Scenerio 2 Assuming the 1.2kva 12v with 20A charger connected in parallel to the same battery bank of 2 x 220Ah

The battery bank gives 12vdc and 440Ah. 440÷20=22hrs

Question: how possible is it practically that by mere connecting the bank in series it takes 11hrs but in parallel takes a whopping 22hrs when the charger and battery remain unchanged. I find it odd.

3. A man wants to venture into business so he buys a dozen (12) eggs for 5naira and sells them for 3naira. From his calculation, if he sells 20eggs daily, in 1year (7300eggs) he will be a millionaire. And his calculation is correct. How is that possible?

7300eggs÷12=608.33dozens
608.33dozens x N5=N3,041.67k
7300×N3=N21,900

Pls tell me where wrong.

Seelurd:
Lack of understanding. Read the question again

I understood quite alright. But approached differently with more details.

Focus on proving me wrong.

walexy30:
X+Y=110
X=Y+100Y

Y+100Y+Y=110
102Y=110
Y=110/102
= 1.078k
= N1.08k Appr.
The cup costs N1.08k while the glove costs
N110-N1.078
= N108.92k or N109 appr.

2 100 minutes

3. Impossible

I think x=100y

So 100y+y=110
101y=110
y=1.089 approx N1.09k

Hkana:
Q1 the cup costs 1.08naira (approximately)

Q2 ten minutes

Q3. Tricky though but here goes:
A dozen eggs cost 5naira, that means each egg costs 5/12 = 0.42naira
He sells each egg for 3naira means he makes an approximate profit of 2.58naira per egg

Daily profit from a sale of 20 eggs = 20 * 2.58 = 51.6naira.
A year's profit therefore = 51.6 * 365 = 18,834naira


Now 1naira = 100kobo
Therefore 18,834naira = 1,883,400kobo


Final answer, it is possible for the man to be a millionaire only when the currency is in kobo and not naira.


Cc opeaceo and gendebs

2 correct, but want to share how i processed 3.
1. Is 110/101=N1.09k

2. 20eggs/day for a year is 20x365=7300eggs
7300xN3=N21,900.00k
7300÷12=608.33dozens
608.33x5=N3,041.67k
Profit is 21900-3041.67=N18,858.67k

I would have said imposible millionaire but any number less than a billlion can be called in terms of milllions.

if he had to call an expert to check on what the problem is, The expert will 1stly check the SOC of the battery with a good DMM. that will show whether the battery is still charging on d 4 bar blink or it d battery is on float charge.........my point is There isn't surplus cash in average Nigerian to invest on these inverter stuff u know...what does he gain if he should get 60amp external charger n it doesn't increases his backup?

I get the angle you are coming from.

Dont you think that even before going to the field to start testing you got to do the maths to know if there is a deficiancy in the system. In this case how effective is a 20A charger mated with 2 220Ah battery bank. Not matter the testing, the charger cant produce more than the 20A it is rated which will naturally take a long time to charge fully. If the maths is right at 22hrs that means he needs a full day of charging with public supply at atleast 200vac and 50hz non stop.

You need to ask him if he had had that kind of non stop charge to be able to get that full. If he never had, its not so easy for him to experience that full charge.

Some of what i have said before comes my personal experience with the same inverter. I know how it behaves. For instance, when the inverter has fully charged to the extent it no longer flashes the 4th bar and grid power supply fails for 2 seconds and returns which mean the battery mode has been entered and exited, the 4th bar will start flashing like its charging. Its going to flash like that for another 30mins - 1hr before it shows full charge again. The question is, did the 2 secs discharge (even with no load) of battery replenished by 30mins of charging? I dont think so. What i think is that it reenters floating charge which will keep the inverter charger in that mode for a while.

Secondly, i sometimes usually know when my inverter is charging on floating or bulk. This i know when we have low voltage of around 100vac from grid or when using generator. When using generator i hear the change in generator sound upon putting load on it, i know the charger is in bulk stage but when no load is felt by the generator i know its on float. I use a 1kva stabilizer to charge the system so when we have low voltage in grind and the inverter is in bulk charging, the stabilizer heats up real bad. But when voltage is above 160, it charges well without me knowing the stage.

I have watch the inverter well thats why i feel its the set up that is incapacitated.

temizeee:
most calculation doesn't work in real life......if u av experience in solar, inverter battery installation u will know what i mean... lol seriously 60/80amp is a wash also do u think a 200ah ba3 would provide 200amp straight? or yr 60 amp charger will pull accurate 60amp from the grid? lolzzz. how do you account 4 a public supply grid producing 90~120vac which is even fluctuating the voltage?

What do you suggest?

If his 20A charger will not do an adequate job, dont.you think he should go higher?

If he gets say 120vac from the public supply, dont you think thats the more reason he needs a better charger.

Am also learning.

Arnod007:
I used a new mercury tubular battery 220amp and my inverter is mercury 2.4kva digital, just bought it a week ago and no matter how long have charged still doesn't have the four bars solid, the last bar always flashing

My guess is you have 2 of those batteries which is 440Ah.

Mercury 1.2 and 2.4kva both come with 20A charger. 440Ah÷20A=22hrs

So you need 22hrs of constant grid power (NEPA) to charge fully.

The charger is simply inadequate for your battery. You can purchase an external charger of something like 60A or better still 80A.

440/60 = 7.3hrs or 5.5hrs with an 80A charger.

EgunMogaji:
I'll always be above you dude, always.

Typical above everyone attitude that led you to change your moniker several times to hide face after embarassing yourself that many times.

You cannot push me to give you the code, you can only ask politely and i will get it for you.

I only respect you because from your history you should be as old as my father. I guess we Nigerians have respect for elders by default, that makes you above me. Happy

Olabamijie:
Thank you, but is there a building code restricting single access to buildings? sure I know safety could be considered but not withstanding, cant something functional be made of this plan?

This is Nigeria, we are not known to follow laws sacrosanct.

Just like i said before, i wont be comfortable in a house with no alternative exit and wont advice anyone as such.

This brings back a thought, i know a certain goverment quarters where the house was built in 1979. The main flat has 2 exits and all windows buglar proofed while the BQ has only 2 independent rooms with one room but windows are not buglar proofed. There is a reason the designer or contractor did what he did.

EgunMogaji:
Oh stuff it.

Answer the question or stop preaching already. Your postings are typically do as I say or the heavens will fall and hence why I always pin you to provide proof and guess what I'll always press you regardless of how much you try to weasel out of doing so.

Just like it was before! You wont see me down there with you.

EgunMogaji:
You don't know what I chose to do or not do so please stop the preaching.

Share the code if you do find it and still care to share.

Thanks.

This officially the third time i am having this kind of fracas with you where you insist on getting facts when i told you already am not in a psotion to do so. Am in a beer palour, you cant force me to go to my pc to get proof for you.

Like the gospel of Christ, you take it or leave it. You can use the option of politely asking to get proof.

EgunMogaji:
If you come up with a building code that specifies this I would love to have it handy.

I don't particularly care about convenience or design ethics.

I know what you mean.

Like i said, i dont have it to quote right now but i know it exist especially with regards to fire codes. You may choose not to follow codes and so many Nigerians choose not to, but i wont do what is not professionally advised.

Egress is what the codes uses. It also concerns number of stairwells for multrise buildings. I cant go into details but some bits of it are in the back of my head.

EgunMogaji:
Is there a code that requires two doors per unit?

I may not be able to quote without researching, but its against design ethics to design a living quarters without an alternative exit.

In some places it is illegal for safety reasons. For convenience it is very necessary to have another exit.

Hello nairalanders, Architects, Builders and Civil Engineers alike, how una dey?

There’s this little problem I hope we can all solve together. The plan attached is a 3beedroom Bungalow my client bought from one of these estate developers here in Abuja. I believe we are all familiar with their clause of having to build in accordance with specified prototype mandated by the developer. My client is a single young man and he feels a 3bedroom apartment is just too much for him for now. We consulted the developer and they relaxed the clause just a bit: we are allowed to alter the interior parts of the proposed plan but shouldn’t shift a block of the exterior (window/door positions MUST remain the same).

NOW.

How best do you think we can alter this plan to get a functional 2bedroom and another 1bedroom apartment under the same roof working with the earlier mentioned restrictions?

Every input will be warmly appreciated.

Thanks.

After about 20secs of thinking, i concluded its impossible for one simple reason.

External doors!

You will be limited to 2 external does which i assume should serve as entrance for each flat. We all know you need 2 external doors per flat usually siting room and kitchen doors.

I cant imagine living in a 2 bedroom flat with only one external door or a kitchen with no external door. If you cant have that, its simply impossible.

My advice is to ask the estate developer for a corner piece where 2 more doors can be introduced away from view. Only then should we can start thinking.

Arnod007:
Oh I didnt have your whatsapp number can you please give me or add me on 08056352358 so we can discuss better.

i will like to know if you have used the inverter battery drained completely before?, Did it just die even with the bar still on 4 bars?

Thanks

Twice i wrote detailed replies but my battery gave up before i hit submit.

I have used all backup a couple of times. It beeps steady for like 10secs before going off after the last bar is used for sometime.

By my estimation 4th bar last from full charge of 100% down to like 40%, 3rd bar 40-20%, 2nd bar 20-7% and 1st bar 7-0%. So the 4th bar last longest.once my 4th bar goes off, i start serious power saving by turning off all appliances i dont need.

Seems like Metuh will spend some time in jail cooling off his bad temper with this new bail when he has not met the other one.

He needs a better lawyer. His lawyer apparently forgot to tell him to say or do nothing without his presence or better still compose himself.

Arnod007:
Hello friend

I also noticed the issue of charging for a long time and yet the last bar will keep on flashing, I charge mine for almost a day plus and the battery last level still flashing.

Also I noticed that the battery level didn't drop even when we don't have light for Almost a day and with all the use, the battery didn't drop a bar.please did you also noticed this? I used 32" lcd,1 ceiling fan, dstv, and a lighting point or is it that the load is not enough to drop the battery.

And i noticed immediately there is light, the inverter start charging from the last bar

Sorry i didnt reply your whatsapp chat. I was on a trip.

My system behaves exactly like you described.

Am truely happy for you. Congratulations and pray that you become a hard working, successful business man.

Are you this naive,its a simple maths the ratio is 90:10.

The simple maths you have failed. Even with only the south ministers, the ratio is more than 10 not counting many others.

Luciferlove:
PMB s appointments so far 90% North...8%SW,2%SS...Keep it up Mr president haters will always hate

Excuse me. You are outrightly biased.

It is easy for you to lump the entire north of 3 geopolitical zones with far more ethnic diversity but want SW and SS to be seen individually even when they are more homogenous.

If you lump the north together like they come from same village lump the south too if you really want to make an unbaised statement.

SSpeter:
I am can never be God. I don't want any of those memories......My brother should know the truth. He deserves the truth!.....i can't be part of a family with a man that nearly ruined my family

Your brother deserves to know, i agree. You are pissed off. Your parents are more matured and see no point in holding such grudge to the grave, i agree with thm too.

I feel telling your brother will make you feel better and will save a lot of future misunderstandings. Be prepared, your brother may not feel the strong feelings you have since he wasnt a witness and may still want you to make peace for the sake of his desire.

If he decides proceed with the marriage (which almost certainly would), i encourage you to tell him how you feel but support him the best you can.

If you declare war on your family, the enemy would have won another fight with your family. If you remain close to your brother, your family may survive. Vengeance is God's. Justice delayed is not denied.

Firefire:
story for the gods...

A wicked and generation of brainwashed children of hate and anger asks for a sign or for Dr. Jonathan to speak up! Sorry, but none will be given it except the sign of the prophet Jonah.

Until APC tells Nigerians the source of their campaign fund, expect no response from the most democratic president in the history of Nigeria.

It is people like you who will first say "burn him alive" when someone is caught for stealing a goat but when your own brother is caught, you will say "the goat was even sick".

Let every man caught for stealing face the law. The one who is not caught will certainly return and his day will come.

I am disgusted by Nigerians who find any means to justify or divert attention from looters. No ordinary Nigerian has the moral right to say what you are saying.

igboboy3:
[size=14pt] There is no need for Jonathan to speak.

This government will only use his words as Season 2 Episode 1 in this Telemundo trial. Lai Muhammed and co will start ejaculating new propaganda with whatever he says.

He has already said he didn't authorise $2.1 billion. What else do you want him to tell you? His ATM pin?


[/size]

NOIweala who released the money said she got the orders to do so by the President. Dasuki said he did, Dokpesi said same and even Olisa Metuh said the president authorised him to spend the money! All of them were authorized to spend the money one way or another by the same man, GEJ.

GEJ saying otherwise is confussing especially that every finger of his accomplices are pointing towards him. If he were'nt respected, he would have been in a cell right now.

ISpiksDaTroof:
And what did they do with the surplus earnings?

Don't let your hate kill you.

Price of fuel fluctuates. So when it goes below N86.50 say N85.50, N1 is saved for the period it remains above the official.

Since it fluctuates, there is the possibility it will go above the official say N87.50. The deficit is funded by the funds saved during surplus. When the surplus funds is exhausted and the price is still at N87.50, the official price is adjusted up. When official price remains too long on the low, the price is adjusted down. That way, govt dont put money from their pockets.

Siena:
[color=Blue]I understand.

I just thought as it's your own car, you would have stripped a lot off before paint, so you have minimal masking, and paint edges.

Lights.
Grille.
Bumpers.
Door handles.
Windscreen washer jets.
Aerial.
Side mouldings.
Side windows (you can wind them down, and mask the aperture).

I do painting too, when I have time, and a booth available to rent when required. I strip my car completely, even going as far as removing my doors, trunk, hood and fenders.

If it's being done by a shop, they strip the car too. There is no better way to prep and paint a car.[/color]

With our mechanics, the more they strip the car the more broken parts you get. At the end after reinstallation, a bucket full of bolts, nuts and clips would have been left behind and you would wonder if the car was fixed back correctly.

When my friend replaced his 2008 Honda Accord engine a lot of bolts, nuts, clips were missing. The entire air resonator box and its associated parts was missing. Engine mount stop bracket is still missing. Any where there is supposed to be 5 bolts, 3 or 4 are installed. All bolts are torqued till they can no longer move. All clips and grommets are broken or lost at the time of stripping. The mechanic didnt have patience when disconnecting connector for O2 B1S2, they pulled out the harnesses from the the connector. The sensor was destroyed in the process. Coolant hermostat housing was broken. PS oil tank was broken too. Gear shifter cable was broken. The list is endless.

It is a lot safer for us to do what we do. Last time i painted my car, the mechanic forgot a huge metal mallet in the boot liner. I had constant noise which i thought to be a failing rear suspension part. The rear wheel was desembled several times looking for the source of the noise but it turned out to be a mallet left behind.

GreatSE:
See how you ended you blind aguement stewpidily after showing so much hatred for SE, Even when you dont know the level of shortchanging meted on SE. These marketers dont see these products at the rate other marketers in the North see them, Ifeanyi Uba who was helping the IGBOS have had his company confisticated and sealed by buhari for useles and baseless offenses. If you know what Igbos are going in the hand of this One Nigeria you will love every SE seccession agitator.

So when northerners and southerners go to depots in Lagos, the depot have different price for them according to their regions.

Where is your brain?

Bryan37:
God
Even people wey never sell fuel for lucozade bottle talk more of filling stations will open their dirty mouth dey rant nonsense?

Let me educate u
Independent Marketers find it very difficult to Buy from direct from NNPC depots in Lagos because of inadequate supply/unavailability of this product to meet demand

So dey buy from independent depots who sells this fuel to them @ d rate of N97 to N120

Come North to Kaduna here, the volume of PMS in d NNPC depot is even excess, they intentionally short change the supply in the South even though d petrol is being imported from the South.

They remove all sort of beauracracy that makes it difficult for Northern independent Marketers to access this liquid.


Mi brother if u know how this Northerners short change southerners on many things u will weep 4 dis country.

Who told u that N60 can buy u a liter from depo

Thank me later.

See this bigot!

There is no depot where independent marketers buy fuel in Kaduna. They all buy and transport with trucks from Lagos just like every body else in Nigeria.

Pipelines have stopped working ages ago so no depot sells fuel in the north.

I dont agree with the pastor at all.

There are things from the past that must be fixed up before we go into the future else we risk taking problems of the past into the future. If out if $2.1billion, $1billiion is recovered and all looters involved are sent to jail, the future is bright as the message will be sent to next set of looters that find themselves in sucnh positions again.

Same way a house built on a bad foundation cannot stand. That foundation must be visited else the house remains a safety threat and unhabitable.
