The math here is quite simple, only problem is the timing, I never managed to do 20 of this type of questions within 20 minutes, but that's usually what they require.
I have to say I am a little taken back by these tests with questions of relevance, time allocation and real world app. I've recently sat one of these tests, didn't get through the final round for the role. Now i've been asked to sit another test for another role. I've never failed a class (after 3 degrees), now i'm faced with the reality of potentially failing 2 in a row lol....hhhmm. Ok rant over.
I really don't understand why these are relevant, in real life computers work this shit out, even if you had to work it out you wouldn't need be forced to do it in 60 seconds. Aptitude tests are not a good measure of work performance!
+James Bird For the same reason IQ tests are relevant. If you are good at mathamatical and logical thinking you will statistically do better than people who are not in almost all logic/math/reason based sciences. This is really basic math.
I score very highly in IQ testing, but quite badly in numerical reasoning tests. Interestingly, I studied a highly numerical subject at degree level, and never struggled with math. I think the problem is that I'm just not a particularly fast thinker, and I struggle with accurately reading and interpreting graph under time pressure.
In the coffee bar test I found It's much more efficient to just simply divide the given population by 100 and multiply that number with the number represented for Ireland on the bar chart. The idea is simply to have the two given pieces of data represented in the same multiplier. So you could either divide the population by 100 to have that number represented as per 100,000 akin to the coffee bar's per 100,000, or you could divide the coffee bars by 100 to have them represented as per 1000 matching the population's per 1000. Once you have chosen whichever way, just multiply the population with the number of coffee bars per x-population. It might sound more complicated than it is, but it's way faster when you practice it. So, 1. Differentiate your data. 2. represent data in like-multipliers. 3. Compute answer.
Shouldn't the second question state whether the % change compared to 2007 was an increase or decrease as the workings and answer are different for these? I assumed office rent increased since 2007.
The test I'm studying for gives you 60 sec per question. By the time i read the question time is almost up, if i try to write something down, its time for the next question.
i was confused for a sec as well. but if you think about it is the same think. if you think in reverse it is like having 253* 1.58 = 253* (1+ 0.58)= 253 (initial value)+ 253*0.58 (increase of the rent)= 399 (final price). you just use the 1.58 to get the final price and not just the percentage of the price increase. hope it helps!
Unless you have a degree in bloody mathematics so many people will do badly at this because it is not used in every day life in normal jobs... people forget the stuff they learnt at school.
bexbubble16 I totally agree with you. I don't know how much these aptitude tests have halped employeers, but I'm pretty sure they moved plenty of anti-depressant and anti-anxiet meds..
+bexbubble16 This is super basic math. lol. That's like saying you need a degree in English to get a good SAT score. If you are good at mathamatical and logical reasoning you should be good at IQ tests, numerical reasoning etc.
I haven't done real math since high school but because the UX/UI Design market is using them. Now since it been so long I have forgotten so much of these. When I did a practice test I felt dumb after 2mins of trying. And now I`m using shlsuccess site. Guys really doing their work well. Now I have 89% for logical test!!! 82% verbal... I recomend!
The math is not hard, need to understand the question and how to approach it however, quite a large number of these questions requires serious problem solving and a multistep approach often requiring up to 3 or 4 minutes! Not reasonable to expect people to solve 18 questions in 25 minutes... actually quite useless tests ..if they disqualify based on volume of questions attempted that are correct. In most cases you can't simply skip a question and come back later, forcing you to guess at the answer for most due to time constraints.
Thanks, but the title is misleading! Your video shows how to "SOLVE" but not how to "ACE" numerical reasoning tests. I understand some people have problems with basic arithmetic and I'm glad your video helps in this manner. However, to do well in these tests one needs to be able to assimilate the question and solve in under, typically one minute and I was hoping your video will provide some tricks on how this can be done. Surely your solutions are not derived in less than one minute.
I agree with you: 43% = 0,43 If they meant increase, it should be 143% = 1,43. 100% is no change, not the double. The guys that make these tests don't know math rules...
Thanks for the nice little lesson in backtracking percentages ;) doing a numerical reasoning test for wpd tomorrow, i've got the groundwork covered but a little revising so i can ace it never hurts ;)
So what I dont understand is why at 13:00 he divides Niscosia by 1.58 to get 253. Why cant I x it by .58 then minus it off the original? What situations do you divide by a percentage??
+apc467 It is faster this way. 1. (58/100) * y = x y + x = 399 x=146.7 , y = 252.531 or 2. y = 399/1.58 After practice you will realize that option 2 is the same as option 1 but faster. Try it with any number and you will get the hang of it. You can use this simple "technique" in problem you come across.
It feels like 58% decrease of 399 is 167.58. So isn't it supposed to be 0.58 x 399 (231.42), then subtract the value from 399 (399 - 231.42) to calculate the decrease in value? or simply 0.42 x 399 = 167.58
I don't know if you still need the answer but think of it as you know that in 2008 there is 399 and 2007 is (x) so the equation is 1.58(x)=399 as there is a 58% increase. therefore you move the 1.58 to the other side to get (x) which is what he got
Why do you specify May 2008 when it's actually an annual amount? In the May 2007 as well, it's an annual amount increase. Surely such headings are not real world examples? Its also very misleading and cryptic to any reading the report. Naturally I would think that since its a positive number, its a positive increase. You also not calculating actual amounts for May year on year. One could then rather use actual amounts for May year on year.
The coffee bar question is worded incorrectly. It asks how many more bars there were in 2010 than 2005. 31 vs 28. The population increase is irrelevant and not asked.
its 1.1 because its a 10% increase, i.e. 100% + 10% so its faster to multiply by 1.1 (1+0.1) than by 0.1 and then adding the extra to the original hope that makes sense...
So you just round all your decimals? Maybe that should be mentioned at the beginning? Especially with the rent question, I assumed pennies count. As a result, my answer is 0.45 off. Oh well.
59.5 for the second. Is it imperative that I approximate the values? Do you have any idea by chance if you have such questions for CITI Group ? I ask because it took me like 6-10 minutes to finish the last question (without using any calculator though) and I know we have 90 sex or so per question.
because on the graph it says population per 100,000 so you would divide the total population by this and then multiply by the figure on the graph so you can find out the number of coffee shops for that population
In numerical reasoning 2 I got $59.55 is that acceptable, Cuz Dubai's Monthly rate in 2007 is 80.59 While in Nicosia is 21.04 and I used the same solution... Estimating it will result to 60

In the second question, I think it's not correct to say "Change compared to May 2007" without clearly stating if it's a decrease or increase.
Thank you ben your videos help me a lot. I have a test tomorrow at The Valero Refinery. Pray for me!
How was your test, I had prayed for you even though I am 10 years late?

Some questions they expect you to get quick than a minute so it balances out.
Jackmerius Tacktheritrix yeah but there are some tests where you only get a minute then it moves on if you don't have an answer
i was confused for a sec as well. but if you think about it is the same think. if you think in reverse it is like having 253* 1.58 = 253* (1+ 0.58)= 253 (initial value)+ 253*0.58 (increase of the rent)= 399 (final price). you just use the 1.58 to get the final price and not just the percentage of the price increase. hope it helps!
thanks a lot for the tip - mulitiplying by 1.1 saves so much time than first multiplying by .1 and then adding the number - which was what I was doing
i have one in a few days. Hoping this will help me, I am useless at maths and timing is soooo much pressure.
Because is a 10% increase of its actual or 100 + 10= 1.1 cause 100=1 and 10 =0.10 Hope that helps

+August come on now, this is specific, school children have much better chances in these tests than grown ups who practice real work issues...
Most people who have gone to college or university at any point in life will out-perform most people who have no higher education.

he teaches you how to solve it, its up to you to then practice these tests so you know what solution to use.
So why for the percentage calculations, do you use for example, 1.43 and not 0.43?
1383=x+x(0.43)
(Office Rent 2008) = (Office Rent 2007) + (Office Rent 2007)*(% Increase)
I agree with you: 43% = 0,43

because on the graph it says population per 100,000 so you would divide the total population by this and then multiply by the figure on the graph so you can find out the number of coffee shops for that population
