To cut it short, this is where I will end my write up. I am sure one of us must have gained one or two things. Just master any technique that suits u to b quick and accurate.

Well, u must have noticed some people finishing numerical test easily and going back through them when one is still busy racking his/her brain.

They are not really genius and intelligent per say as you can be better than them. But they did what you haven’t thought of doing:

THEY MASTERED THE SHORTCUT TECHNIQUES

INFERENCE

Wow! with the shortcut method, I can calculate this problem under 10 seconds. Absolutely fantastic. Note how I deduce the above shortcut technique:

From the table, GDP Per Capita is also (GDP / Total Population)

Employment to Population ratio is also (Working Population / Total Population)

When you divide, Population will cancel Population resulting to (GDP/ Working Population).We all know the Working Population of a country are the Employed Persons.

SHORTCUT METHOD

In 2007, GDP Per Capita (GDP / Population) = $22188. In 2007, Employment to Population ratio: (Working Population / Total Population) = 65.8%

Therefore, GDP Share Per Employed Person is GDP Per Capita/ Employment to Population ratio = $22188 / 65.8% = $33720

From the attached

NORMAL METHOD

From the question, we are considering 2007. First Determine the Population in 2007.
Population in 2007 = Nominal GDP / GDP Per Capita (GDP / Population)
= $1049.5 billion / $22188
= 47300 billion people

Employment to Population ratio = 65.8%
Employed Person therefore is = 47300 * (65.8 / 100) = 31123.4 billion people
GDP Share = Nominal GDP = $1049.5 billion
Employed Person = 31123.4

GDP Share Per Employed Person is = $1049.5 billion / 31123.4
= $33720

Acedude: This is absolutely amazing DMainMan! Thank you for this. No doubt Shl questions can sometimes be a hard nut to chew but the simple steps you outlined here can make it a piece of cake.lol..
(I noticed some approximations were not made to the nearest highest num(e.g you apprx. 6589 to 6 and not 7 in the lingerie question) or it doesn't matter?)

Kudos to you!

Thanks for ur observation but it doesnt affect the final result. Take care

INFERENCE

Imagine you solving this using the Normal method with no calculator. Will one decipher it? But with shortcut method, we can calculate this less than one minute with no calculator. Remarkable!

SHORTCUT METHOD

Of course, everyone understands this approach now.

Add the total number of Lingerie sales:

6 + 6 + 8 +7 + 9 = 36

Then calculate the total number of sales in the table:

6 + 6 + 8 +7 + 9 + 1 + 5 +8 + 2 + 6 + 5 + 6 + 4 + 1 + 6 + 3 + 1 + 8 + 6 + 6 + 8 + 6 + 9 + 8 + 7 = 142

Lingerie Portion is: 36/142 = 0.2535 which is the closest to (1/4)

From the attached

NORMAL METHOD

Add the total number of Lingerie sales:

6258 + 5987 + 7548 +6794 + 9874 = 36461

Then calculate the total number of sales in the table:

6258 + 5987 + 7548 +6794 + 9874 + 1354 + 4512 + 7894 + 2365 + 6589 + 4785 + 6587 + 3564 + 1247 + 5897 + 3254 + 1254 + 7894 + 5658 + 5655 +7854 + 5648 + 8999 + 7844 + 6542 = 141857

Lingerie Portion is: 36461/141857 = 0.257
which is the closest to (1/4)

INFERENCE

You should now realize y most of the job test agencies give little time aptitude test. They don’t expect u to use the Normal Method to solve always hence the test time is actually being justified. Just look at the option. 6/35 = 0.171 in fact correspond to (17/91) = 0.171 as opposed to 0.169 we got using the Normal Method. This evidently tells you the solving style they hope you will use.

SHORTCUT METHOD

The approach here is the same as the former. Now let’s solve it:

Total Unit sales in 2010 is: 9 + 7 + 6 + 6 + 7 = 35

Total Jeans in both 2006 and 2007 is: 1 + 5 = 6
Ratio = Total Jeans/ Total Unit Sales
6/35= 0.171.

Check the options. (17/99) which is 0.171 is the answer

From the attached

NORMAL METHOD

Total Unit sales in 2010 is: 9874 + 6589 + 5897 + 5655 + 6542 = 34557

Total Jeans in both 2006 and 2007 is : 1354 + 4512 = 5866

Ratio = Total Jeans/ Total Unit Sales
5866/34557 = 0.169 app 0.17.

Check the options. (17/99) which is 0.171 is the answer

INFERENCE

Can one really get to the bottom of this question using the Normal method? I don’t think so in examination condition. You are going to spend considerable amount of time in solving with Calculator talkless of u solving it manually. Well, this is one of the astounding worth of the Shortcut technique.

SHORTCUT METHOD

When solving a problem like this, approximate the first digit to the nearest single number. Don’t take into consideration of the whole. So, you are going to work it out like this:

Lingerie: 5 * (6 + 6 + 8 +7 + 9) = 180
Jeans: 13* (1 + 5 +8 + 2 + 6) = 286
Formal Suits: 32 * (5 + 6 + 4 + 1 + 6) = 704
Cardigans: 30 * (3 + 1 + 8 + 6 + 6) = 720
Shoes: 26 * ( 8 + 6 + 9 + 8 + 7) = 988


Answer is Shoes, the biggest production cost.

NORMAL METHOD

Here just sum up the total number of sales then multiply with Production Cost per item.

Lingerie: 5.21 * (6258 + 5987 + 7548 +6794 + 9874) = 189961.81

Jeans: 12.58* (1354 + 4512 + 7894 + 2365 + 6589) = 285742.12

Formal Suits: 32.42 * (4785 + 6587 + 3564 + 1247 + 5897) = 715833.6

Cardigans: 29.83 * (3254 + 1254 + 7894 + 5658 + 5655) = 707418.45

Shoes: 25.75 * ( 7854 + 5648 + 8999 + 7844 + 6542) = 949840.25

Answer is Shoes, the biggest production cost.

SHORTCUT METHOD

There is actually no need for u to utilize the actual value fund when calculating. Simply multiply 10% China holding by 11% which was moved to India and then add the result to the 9% India holding. Afterwards take the percentage.

(10/100 * 11/100) + 9/100) * 100
(0.011 + 0.09) * 100 = 0.101 * 100 = 10.1%

INFERENCE

How simple numerical reasoning test is if u can master the shortcut technique. Think about the time and stress you would have saved in solving this.

From the attached:

SOLUTION

N ORMAL METHOD

Total Value of China holding: 210m * 10% = 21m
11% of China holding: 21m * 11% = 2.31m
Total existing value of India holding is : 210m * 9% = 18.9m
Total new value of India holding is 18.9m + 2.31m = 21.21m
The proportion that India will represent is:
21.21m/210m * 100 = 10.1%

SHORTCUT METHOD
Here, we apply the Arithmetic Progression (AP) Formula:
((First Value (2009) + Last value (2012)) * Number of Segments) / 2
Therefore, ((10 + 15) + (22 +32) + (15 + 17) + (5 + 7)) * 4) / 2 = 246
From the option, the closest answer is 245 million which the answer is.



INFERENCE
The problem of the Normal Method here is that you are more prone to mistake when a very large data is needed to be calculated and also can be time-consuming. Remember that Dragnet and some SHL test (Mobil test for Postgraduate holders) prohibit calculator. It is advisable to master this shortcut technique so u will not only be quick but also for precision and accuracy sake.

From the attached diagram:

NORMAL METHOD

To solve, just add every figures in the bar chart together:

Segment 1: 10 + 12 + 14+ 15 = 51
Segment 2: 22 + 24 + 30 + 32 =108
Segment 3: 15 + 16 +17 + 17 = 65
Segment 4: 5 + 5 + 6 + 7 = 23
Add together: 51 + 108 + 65 + 23 = 247

[b]NOW LET'S GET STARTED[b]

Credit should also be given to a nairalander “achmed1” and of course not forgetting “Graduate Monkey”.

NB: When solving some Numerical reasoning test, sometimes the answer you get wont b in the option. This is specifically made to make you lose confidence, so don’t panic at all. Choose the option that closely matches what you get as your answer.

We will unravel using the Normal method or Shortcut method.

Well I am already through but dont know y nairaland server keeps screaming being overwhelmed wen trying to create a new topic
