McWhillion: A petrochemist yet to define his career path.

you wan chop oyel money too abi? Hehehe. Time for work. Hv a nice day bro.

Cool. Okay, i guess we both need to improve on our 'question-formin skills' ..
I is a statistician.. Who art thou?

McWhillion: Let’s look at it this way, the two trucks run simultaneously, also there odometers read the same figures at the same time but there rate of depreciation is different.
Let’s assume the following represents our rate of depreciation,
(V1-V2)/M
Where, V1 = first value of the truck, V2 = final value of the truck and M = mileage.
We’ve already determined the rate of depreciation for the two trucks as #6.249/km(R1) and #7.721/km(R2) respectively.
The question wants us to calculate for a period where the two trucks will read the same mileage and be worth the same value (i.e M and V2 are the same for both trucks)
If this is true, our equation becomes,
For truck 1---- (#3,500,000-V2)/m = 6.249
For truck 2---- (#5,200,000-V2)/m = 7.721
The above becomes,
3,500,000-V2=6.249M…(eq.1)
5,200,000-V2=7.721M…(eq.2)
Solving for both unknowns we get V2=
(-)#3,716,916,
and M= 1,154,891km
Although that answer is hypothetically impossible but mathematically right. If I had adjusted the values we would have gotten a positive answer.
The two equations can be likened on to two unparallel lines which must surely meet. The cordinates of that point where they meet is what we just calculated for

this is what i call 'manipulation' bro.. Good work bro. Two parralel line doesnt meet, do they?! Hehehe..

But come to think of it, we can always find the different mileage for the two trucks at the same residuals as long as they maintain their respective decay rate. Example of this is the last question. Accordint to ur solution(and you already affirm this), ur answer is logical but not realistic. So i dont think their will be ever be a M for which V2s are equal. I stand to be corrected though.

McWhillion: Dont forget that they don't have the same rate of depreciation.
Truck A will be sold off first before B.
Since they have same meter reading, at 400,050km, Truck A will be worth #1m while truck B should cost more but there would be a time the two will cost the same at the same mileage reading.

bros, i still do not think so o. I may b wrong though. They move together, they read same on mileage independtly. Second truck cost more than first.. We lookin for a mileage when they cost the same price..

For truck A,
3.5-6.25X=Y

for truck B,
5.4-7.72k=Y

where Y is the residual, and x and k are the respective distance each truck would have travalled so as to hav the same residuals.. Just thinkin out here.. Think it too bro.

i get ur point.. Lemme see if i can manipulate my way through..

McWhillion: Linda puts money in two investments A and B which paid simple interest. If annual rate of investment of B is 1.5 times of A, what amount did Linda put into A?
a. Interest for 1yr is $50 for A and $150 for B.
b. Linda put twice the amount of A into B.


I'M KINDA CONFUSED, HELP!

insuffient data o..

McWhillion: McWhillion Transports has acquired two trucks to carry different types of cargo. One costs #3,500,000; the other costs $5,200,000. The company expects that the first will last 400,050 km, after which it can be sold for salvage for about #1,000,000. The other will fetch the same salvage price, but will last 544,000 km. The two trucks convoy together, so they always show the same mileage readings.
If the value of each truck declines at different constant rates for every mile driven,
Calculate the rate of depreciation of each vehicle.
At what mileage reading will the residual values of the two trucks be equal?
At what mileage readings will both vehicles cost #500,000 each?

solved it here already, i shouldnt post it since some1 has already privided the solution.. The second question, i cant inteprete it. Since they have different depreciation rate and they convoy together, i dont think they will be a km/mileage when they will have the same residuals simulteneously...

Why do y'all keep beggin mods now?!
my friend, how well do you read ur bible? The answers you seek are in the bible. Read the Gospels and acts then you'd see when prayers were loud and when they were silent.

Whether silent or violent, God's answers both.. But i tell, you need violent prayers esp in deliverance and warfare.

What i dont suscribe to is disturbin neighbors with prayers.. You can pray loud as you want in church..

Besides, all you just need is power...!

this is simple now.. Just lookin at it, i think 'twill give you a simultaneous equation or so.. Though i am not sure and dont wanna jump into conclusion..

Nna mehn, kissing is so important o esp if it happens between people that hvae true love for each other.. The feelin, the smoothness, the bond, the commitment, the yearn, the desire, the affinity, the..., the.... ... Tthe effect of kissin of people genuinely in love cannot be overstated; esp in marriage...

Can someone explain to me ow i missed this great thread?!

jayyungg: Bro 'll think differently. No insult! *Peace*

aii' bro. No P.

Age is not merely a number; motive for gettin into the relationship makes it just a number. Some ladies marry younger men coz they b gettin old- biological clock ish. Some be doin it coz of money-gold digin/finacial security. Some men be doin it coz the woman is boxed-up or outta pity. Those are all conditional love. Some pople do it out of true love..

Which kain mentality be this na? Because you gave her 1k means she'l accept you?! Someone needs reset!

'talk true', you hated maths back den, right?

missdebs: *wiggling hands* den den de den den i wee teel ur mummy 4 u

i remember this tune.. Bless us!

busterr: 'remain for me ice cream' instead of can i have some ice cream


'i'll tell for you' instead of i'll report you.

i remember this.. Hehehe.

Wel, if you were a kid back den in the late 80s through the mids 90s; particularly at primary schools den, if you didnt speak these 'englishes', den i guess you didnt grow up in lagos. Was born and had me early life at Iju, Ifako Ijaye.. Oh, bless Late Cheif Majekodumi, proprietor, Ifako International School. Those days before the ghananians went away-sorry-before 'ghana-must-go ' saga; when these people were all over Naija.. Dem plenty as teachers for privates schools at ifako through ogba.

Here we go..

Scenerio one:
this naugty girl wont just let me be, keeps disturbin me in class.. Reportin her will be like: "Uncle/aunty, come and tell her o!"


scenerio two.
you had a fight with ur classmate; you fightin pair were called out to the front of the class by the class teacher and asked to explain.. Facing a stern-lookin teacher, you tryin to get vindicated be like:
"uncle, i did not know o. As i was walkin, he now come and slap me, an' i slap him back, he now come and blow me, an' i come and blow him back....

Scenerio three.
Your mom asked you not to play out today. Immediately you saw her shadows leave the street, you went on a playin-spree! Unlucky you got caught and she gave you the beatin of ur life!
Later that day, your friend asked you what went down, you writhin in pain b like:
"my mommy say i should not come outside, an' i come out and she now beat me..!" you said that with a long face expectin some smpathy from ur friend. She replied you, "ngabti you self is stubborn, you too should not 'kukuma' have come out now." 'kukuma' is yoruba phrase which means "should'nt" or 'should' dependin on how you use it in a speech in yoruba. The right spellin should be " kuku ma" or so.

Scenerio four.
You went playin all day, you forgot you hadn't had ur lunch. You rushed home and asked ur lil' sis who had bn home playin with her 'inventory':
"you have eat?!"

add yours and lets laff our ribs off..!

Oh my! You'v just described me..
You didnt include these:
1. We dont like to percive things like others; we want to look at things diiferently.
2.we like to take risks and aint afraid of makin mistakes.
3. Some of us really have weird senses of homour...!(you kinda mentioned these anyway.)
4. Most of us are hardcore introverts, some are 70% introverts.
5. We are always reserved.
6. We want to always try to find out 'why' before 'how'.
7. We'r not very handsome/beautiful. We'r always just fair/presentable mostly, others are kinda ugly.. :p
8. Most of us men have fairly large noses..
9. We are not fashion freaks but dresses smartly.
10.we are honest/faithful lovers.. (Realy? :/)

will add more later as i remember me.

Talkin misplaced priorities..! North is burnin and all these peasants could think of is fightin for some dudes who care lower than less'bout 'em..! Great...!
Here's some o' dem comments me found on sahara's reporters FB wall/page:

the pained guy:

Idris Muhammad
When would my muslim brothers in the North stop all this foolish protest on behalf of muslims in the Middle East on the basis of religious affinity? How many of them have protested on our behalf ever since we are suffering from boko haram? Nonsense!

The ardent believer:

Yusuf Muhammad
The Holy Prophet (SAW) Said "WHO SO EVER WAKES- UP AND DOES NOT CONCERN WITH WHAT HAPPENS TO HIS MUSLIMS BROTHERS, IS NOT AMONG THE MUSLIMS!"

reasonable fella:

Golmetne Gofwen
But are the muslims in Gaza and the whole of middle East seeing A nigerian Muslim as their brother? because iam yet to see any protest in the middle east regarding BH problem we have in Nigeria

religion can be good, if understood. You cant be a true beliver if you merely obey 'rules' wih deep down no moral/spiritual foundation with/by which you measure deeds.

Stop being slave to ur arab masters/pastors/imam.. God is not 'retricted', He is everywhere and he lives in you!. He's love; gave us love through Jesus Christ. Accept him or die!

Lets make this really simple right? So 'mma 'quantify' the variables.
Let unit cost price of a tin of milk be N8.
C.p=N8
total cost of 4 tins= 4*8= 500% of c.p=N40
average profit on 4 tins= 5% of 40= N2
Let unit profit,i.e, profit on each tin of milk had Taye stuck to the stipulated price by law= s.p-c.p=x.

By law, each tin of milk should be sold for the same price by Taye. Consequentially, this results to, average proft= unit profit
hence, unit s.p=unit c.p+unit profit=2+8=10.

Unit Mark-up price= 140% * 10= N14
total markup price= 14*4= N56.

Buyer's total = 1250% of unit c.p= 1250/100*8= N100.
Change returned= 100-56= 44.

New unit profit = 14-8= 6

1. New unit profit is 6/8*100= 75% of unit c.p

2.fraction of the buyers change is 40/44= 10/11.

Tinkybabe: You must be a business man paranorman

primary cost price of 1 milk tin = m
secondary cost of 4 milk tins =(500%)m =5m
" " " " " " " " 1 milk tin =5m/4 =1.25m

Price of one milk at stipulated rate = r
profit from total sale =(5/100)5m =0.25m profit
therefore 4r= (5+0.25)m = 5.25m
r= 5.25m/4 = 1.312m

Final selling price of each milk = [1.312m(40%) +1.312m] =1.837m
FSP of all 4 tins =4 x 1.837m = 7.35m

Customer gave 1250%(1.25m) = 15.625m


1) New unit profit = (1.837-1.25)m =0.587m
% profit in unit cost price = (0.587/1.25)100 = 47%

2)buyer's change =(15.625 -7.35)m = 8.275m
% fraction in total cost price= (8.275/5)100 =165.5%


Panoraman it seems you have a knack for giving unclear questions..
Is the cost price referring to Taye's cost price?
Is the selling price,the price it was sold to Taye or the stipulated selling price?

**confused**

you know you problem, you too know book! You just thinkin too much...
Taye doesnt have control over cost price. Cost price is always the cost of purchasin all 4 goods or the cost of a unit of the commodity. While the sellin price will always be the amount he sells the goods to a customer. You are thinkin too much dear.

priscaoge: Lmao!!!!

kobonaire: If each of them had A, B and C cars respectively

After the first exchange then each respectively has:- (A-B-C), 2B and 2C

After 2nd exchange: (2A-2B-2C), (3A-A-C), 4C

And final exchange: 4A -4B-4C, 6B-2A-2C, 7C-A-B

And since we are told that after the final exchange, each has 24 cars, we can thus form 3 equations for our 3 variables :-
4A -4B-4C = 24,
6B-2A-2C = 24 ,
7C-A-B = 24.

So solving these 3 equations yields
A=39 : Wale
B=21 : Femi
C=12 : Dele

@paranorman how were you able to compute yours, hope not mentally, then you must be a Math PhD

nope. Follwed a similar steps to urs. Na phone i dey use. Stressful to type solution when 'm not on my PC.

Taye is a retailer. He went about his business to purchase tins of milk at a famous wholesale store.

The consumer price regulatory commission, an agency solely established to protect consumers from exploitation and promotes fairness in competition had already, by law, stipulated the uniform retail price of different consumer goods, including this particular good Taye wants to buy. The prices' list are printed on and displayed at every store accross the country.

Taye bought 4 units/tins of milk whose cost totals to 500% of the cost price of a unit commodity of the milk.

Had Taye sold at the stipulated price by law(he was suppose to sell a this price), the average profit gotten from the sale of the four tins of milk would'v been 5% of the total cost price he bought all 4 tins, but he sold all 4 tins to a gullible buyer at a mark-up of 40% on the sellin price of each tin of milk.

The buyer handed a naira note which was 1250% of the cost price of a tin of milk and Taye handed over her change/balance.

The new unit profit is what percent of the unit cost price?

What fraction of buyer's change is the total cost price?

kobonaire: ok interesting..., what background is this question? Accounting/Finance?

wel, you may tag it an if you want. Had none on my mind. Another question is coming up lately. I'd want you to specially attemp it. This is an invitation to try it out. Stay tuned.

kobonaire: Let's say Kelly initially had x Naira. So if she too 20% then
Money taken to market : 0.2x
Money left at home : 0.8x

Radio initial listing price was 25% higher than what she took to the market which means
1.25 * 0.2x= 0.25x

Seller adjusted price was 50% of what she had left at home => 0.5*0.8x= 0.4x
And this price is a 14 2/7% markup of what it actually should have listed for => 1.1427 of what it should have listed for. (The question becomes ambiguous here IMHO).

Anyway if the original price is y then the mark up price is 1.1427y and since it is equal to 50% of what she left at home=>
1.1427y=0.4x

The difference between the original price and initial price is what percent of total money Kelly had?
Original price = 0.4x , initial price = 0.25x => difference - (0.4-0.25)x = 0.15x and as a percentage of what Kelly had = 0.15x/x = 0.15 (15%)

What percent of the profit is the mark-up price? Isn't this simply the mark up? I don't get the question, please clarify @paranorman

[size=13pt]UPDATE[/size]
So the OP has responded saying that the answer to the second question is "INSUFFICIENT DATA" .... abeg, that was rather disappointing, why ask us a question that does not have an answer (simply admit you messed up the question ) ..... see the post here

nah.. Its insufficeint data bro. Profit is sp-cp.. Cost price of the goods were not stated; whether explicit or implicitly. I intentionally contructed it that way. If you'r used to this kinda question, its a common tin.
