Janis has an MBA and has been in school for 1/2 of her life. Carol is 30 years old and started school later, having only been in school for five years. If Janis is four years younger than Carol, how long has she been in school?

A. 13 years B. 15 years
C. 18 years
D. 20 years
E. 26 years

Hi guys,

Is there any sites to get questions like this or similar to this or aptitude test questions.

And can anyone give me an explanation to the answer. It's A but I'd like to know more than 2 ways of getting the answer.

Thanks

2 ways?

You just ignore all the pointles info, all you need is carols age, the fact janis is 4yrs younger and how much af her life janis spent in school, the remainder of the question is pointless info designed to throw you.

Janis is 26, she pent 1/2 her life in school => 13yrs

Thanks for that.


I so hate aptitude test.

Contradiction in assertions. If it's designed to throw you, then it's not pointless!

So did a couple of more test and I can say that I'm good as useless.

Majority of them point out to J.C maths which has basically gone out of my head.

Here's an example



Uploaded with ImageShack.us

For example the question above. what was the population of ethopia in 2000 ? which I did 64.81/997 x 1m = 65mill

ii)

using the same technique the population is 6million.

60% of work is .6 x 6m = 3.6m
unemployment rate = 3.6 x .10 = 360000

iii) percentage increase in total GDP from 1998 - 1999

58.08 - 50.6/50.6 = 14.8

iv) This is where I'm stuck on. GDP per workforce.

workforce being 55% is 3,025,000.

Think you lost a zero there - should be 60 million.

Looks correct.

The quickest way of doing this is to divide the GDP per head of population by 0.55, which gives $2000.

Slightly longer way is to find the size of the workforce:
The population in 1997 was, by same technique as before, GDP / (GDP/pop.) = 60,500,000,000 / 1100 = 55,000,000. (55 million)
The workforce was 55% of that, which is 30,250,000, as you had ALMOST correctly found (missing a zero again - out by a factor of ten). That is the number of people in the workforce. So, you need to divide the total GDP of the country by that number to get the required quantity:
60,500,000,000 / 30,250,000 = $2000.

Beautifully done. thanks.

Going to do more of these and some others.

Rest assured will be back soon.

Hi again,

I came across my old friend.

My understanding is there are two tables joined as one, one on the left and on the right. And if you buy ion BULK you get a discount.

Is there anything else that I'm missing.

Your logic looks ok to me.

Thanks, tried doing this question last night and no joy.

This what I got

Starting from office staff.

its 212 x (3.26 + 7.9 + 18.64) = 6230.68. Those 3 numbers are from shirt trousers and shoes. The footnotes is confusing, but it might be there o put me off.

If not then my calculations for admin workers is all wrong.

This are my remaining figures.

Sales = 64(7.64 + 4.05 + 20.32) = 2048.647

Senior = 16(8.64 + 3.23 + 28.64 ) = 648.16

Delivery = 33( 8.26 + 4.25 + 23.65) = 1193.28

Warehouse 212(7.49 + 3.26 + 8.64) = 3291.68

Adding them up = 13412.44, which is clearly wrong

Possibly it could be my interpretation of the admin workers uniform. I'll try out something different.

freeze4real

Seems we have a winner.

Re-doing the calculations for admin staff.

office 212 (76.15 + 18.64) = 20095.48

sales 64 (85.64 + 20.32) = 6781.44

senior 16 (112.35 + 28.64) = 2285.84

Delivery = 33( 8.26 + 4.25 + 23.65) = 1193.28

Warehouse 212(7.49 + 3.26 + 8.64) = 3291.68

Adding this gets 33,617.12, close to E

EDIT : Apparently its still wrong

The answer is 12843.


Is there any way to do this faster ?

Where are you getting those numbers from???? For example in the first bit for office staff you have" 212 x (3.26 + 7.9 + 18.64) = 6230.68". Where are you getting the 3.26 or the 7.9??

Anyway, if everybody is wearing the same thing you don't have to break it down into the different categories. (You can if you want but it's a bit slower).

In total there are 437 staff members to buy for.

So to get you started, the trousers cost will be [latex]437 \times 7.49[/latex].

Do the same for Shirt and Shoes and add the lot up.

3.26 is the shirts, and 7.49 is trousers.

Since the no. of staff is 212>100 they get thee discount for buying in bulk. Thats how I'm interpreting it .

Doing what I suggested above will give €12,843.

Yes that's right. Dunno what I was looking at. In your op you use 7.9 NOT 7.49 for the trousers.

Wow, thanks didn't realize that my self.

TheBody

Do you see the mistake you are making? If everybody is wearing the same thing, you can make ALL the order at the +100 discount rate.

freeze4real

I just did, and to do the sum faster.

437( 7.49 + 3,26 + 18.64)

TBH it didn't even come to me.
