What was your response to these @OP
Before I ll say mine

gmacnoms:
1.1
1hr40min
Impossible

Even me wey be olodo for maths know say the answer to number 2 na 10mins

gassdon:
Is like you applied as Mathematics Teacher!
Ok. My answer.
Dear employer,
This is not the solution to your company problem(s).

hehehehehehe. dt answer was so kul

Fortune02:
1. 1.1
2. 10min
3. 5/12= N0.4166667 per egg
3 - 0.4166667 = N2.5833333 profit per egg sold
2.5833333 * 20 = 51.666666 profit daily
51.666666 *365 = N18,858.333 annual profit

Going by the info given he will make approx N18,858 in a year. That's N0.019mil so its possible

Thanks 4 d reasoning...millionaire indeed...

this kind of reasoning or problem solving does not make one smart, it's just dividing, multipying, addition and subtractions, real problems in life can only be solved by the Divine...if in anything you be otherwise minded Elohim will reveal this to you

Owww!! I hate calculations.all I want is answer.just give me the answer.

@OP Watch dis
Q1,
Glove=G; Cup=C
G+C=110 .............(1)
G=100-C ..............(2)
from (1)
G=110-C ..............(3)
Also, from (2)
C=G+100 ...............(4)
insert (3) into (4)
C=(110-C)+100
C=110-C+100
C+C=110+100
2C=210
C=210/2
C=105
Therefore, d cost of glove is 5Naira while fat of cup is 105Naira; Since d question says The cost of the glove is 100times more than that of the cup
Q2,
Answer can be 10Minutes or 100Minutes, depending on d explanation (D question is not complete)
for 10minutes,
if 1 machine is responsible to produce each donut
for 100minutes,
if d donut has to go through each of the machines
Q3,
12 eggs bought @ d rate of 5naira & sold for 3naira?
Even if u sell 100 crates per day, the business will continue to record a loss of 2naira per crate. Therefore, I don't think it is possible to profit.

Quad Erat Demonstrata

Your equation 2 should be:
G=100*C

opeaceo:
1. the cost of a cup is 1.1 unit

2. 10 minutes

3. I don't think it is possible.

I think the number 2 ans is 1m

Ok. My answer.

Dear employer,

This is not the solution to your company problem(s).

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

You sabi!!!

Exactly...

These are basic aptitude test questions. The concern should be about how much time one is given to answer them.
So OP, what was the time allowed?

3. 5/12= N0.4166667 per egg
3 - 0.4166667 = N2.5833333 profit per egg sold
2.5833333 * 20 = 51.666666 profit daily
51.666666 *365 = N18,858.333 annual profit

Going by the info given he will make approx N18,858 in a year. That's N0.019mil so its possible

correct is possible

Wit all dis jamb calculation nw salary fit no worth am..

OP was there options of 'call a friend' or 'walk away'









































I honestly wish I know mathematics as much as I would love to....

















































Success....

Even though I love brain teaser, but how does this help the company grow.

Come to think of it the company fit be tele-communication company.

I think the number 2 ans is 1m

I think it's 10 mins bro.

10machines produce 10doughnuts in 10minutes. That means 1 doughnut is produced in 1 minute.
Therefore each machine contribution per minute is 1/10.
For 100 machines: 1 minute production = 100 * 1/10 =10 doughnuts.
Since 10 doughnuts take 1 minute, therefore, 100 doughnuts will take 10mins.

So far so good, this has not solve the problem of mathematics teacher. If they are good, let them teach themselves

3. I don't think it is possible.

I think 3. is possible using d "Time value of money concept".. there are calculations to that effect using compounding factors

buh it's a tough one all d same

These are basic gmat questions na

For 100 machines: 1 minute production = 100 * 1/10 =10 doughnuts.
Since 10 doughnuts take 1 minute, therefore, 100 doughnuts will take 10mins.

The answer is 1 minute.

10 machine= 10 doughnuts = 10 minutes
1 machine = 1 doughnut = 1 minute so if we have 100 machines with each machine producing a doughnut in 1 minute, we would have 100 doughnuts in 1 minute assuming they all produce at the same interval.

LastMumu:
question 1
Equation 1 is Q + C =110
Equation 2 is Q = 100C

If Q + C =110

100C + C =110

101C =110

C = 1.09

The cup costs N1.09k

Question 2 is 10 minutes

Question 3: it is impossible for him to be a millionaire.

Your equation 2 is incorrect. You did not read/understand the English wording properly. It says 100 times MORE, not 100 times! So it should be
G = 100C + C

The answer should be 1.078 naira for the cost of the cup and the cost of the glove should be 108.921 naira!

Question number 2 is one minute

odimbannamdi:
So i was invited to a job aptitude test in Surulere 2days ago. 3 questions caught my attention. Even though i was quite sure of the answers i provided, i still want to ask guys here for their perusal on them


Here they are:

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?

2. If it takes 10 machines 10minutes to make 10doughnuts, how long will it take 100machines to make 100doughnuts?

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

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

abbey621:


The answer is 1 minute.

10 machine= 10 doughnuts = 10 minutes
1 machine = 1 doughnut = 1 minute so if we have 100 machines with each machine producing a doughnut in 1 minute, we would have 100 doughnuts in 1 minute assuming they all produce at the same interval.

If one machine produces 1 doughnut in 1 minute, I guess 10 machines working at the same interval for 10minutes will produce 100 doughnuts, cos each will be producing 10 doughnuts in 10 minutes.

You're right, just went over the calculation again the answer is truly 10 minutes.
