Ι'm an engineer and i feel you so much ! i hate these tests.

*Practice makes perfect! ;)*

You give me hope.

But sir, the problem is that questions are timed and you'll get hardly a minute to finish each. After a minute expires, the system would automatically will redirect you to the next question. This is extremely frustrating and I guess these tests are meant only for mathematicians.

why especially Monday, not another day

It means coming into work on a Monday morning after the weekend off. Your brain is not always firing on all cylinders when you return to work after the weekend. :-P

@@guitarman813 are you a mechanic or something in this field :P

I just bombed at citi bank and I’m usually pretty good at math.

Juan Di Now try using the same method bu5 now calculate 90% of the total expenditures. What you are doing is that you are just not writing that you divide the 3.3% by 100.

thanks diego

Clever clogs lol E=mc2

Thanks.i was totally lost

Lap Chieu Brilliant!!! Haha

WTF this guy can't do it himself when mans has a mans to help mans as well n no timing

Says a lot when the gentlemen brought in to explain these tests doesn’t get the correct answer at the end of it....

Lap Chieu Beecee 😂

He’s a maths teacher at my school lmao

+Bukola Smart I have this exact problem also. I find it really hard to focus and understand what the question is asking me when I'm being timed.

I'm exactly the same i freak out too much and the only advise i would give is that keep doing more practice tests.

I totally agree with you, I'm nearly to finish my bachelor in administration in one of the most important college in South America and we never learnt nothing like this, how can this define if I'm a good or bad for that position?

Araceli Fernández I guess it’s more about how you handle pressure? You have such short time for each question, you need to stay calm and focus on the task and just try your best.

Oh yes

Mr bridges is amazing

@@ch0k3vlogs70 yeah

@@ch0k3vlogs70 Yes, he's the literal best-

Yeah, these tests are more like a filter. They use this to weed out more people and reduce their candidate pools, so they can make a decision much quicker.

100% especially when you're not going to use it in your job

not just doing math, doing it in less than 75 fucking seconds per question

+Moe Al Obaid That was definitely not our intention :-)

I would like to believe so. It was just a notion to simplify it a little more. Thanks !

Hahaha..that's wht I was thinking

Yes@assessmentCenterHQ..to start with, the first calculation is wrong..13% becomes 0.13 as a decimal not 1.3..that alone has turned me off this video

lessie owolabi you’re wrong. It wasn’t 1.3 - it was 1.13. And you put 1.13 instead of 0.13 as you are finding an percentage increase instead of finding 13% of a number.

You may increase your consumption by 15%, but you have different percentage of total family cost which on July is 3.3%. What you have done is that you applied the increase in a 3.5% of total family cost for July too.

if it increase by 13%, it means itself times (1+13%)

multiplying by 0.13 would give you 13% of the original value. By putting 1.13 the one before the decimal point acts as the original value, such as multiplying a number by itself you will get the same number. So 1.13 is the original value plus the 13% increase, easier than finding the percentage then adding it on, it's the same math this is just faster.

This is the problem for me too taking these tests. Nobody explains where they get the figures from

I feel like they explained it kind of weird, but it is a pretty short video: The first step of the problem doesn't really involve the data table at all. You know the June expenditure is $220, you need to find out the July expenditure; since it's a 15% increase, multiply by 1.15 --> $253. The second step of the problem is to find out what the total family expenditure is in July, and for this you need the table. Entertainment in July made up a total of 3.3% of the family's expenses, as indicated by the table header. Here's where I think they lost a few people (and lost me for a minute or two): 3.3% of the total was $253, so I'd write it as 3.3=253. You then write out what you have out of what you want, so you have 3.3% out of the 100% that you want, you have $253 out of an unknown number (N) that you want to have. 3.3/100 = 253/N you then cross-multiply and/or move around the equation so that you're solving for N --> 253x100 = 3.3xN --> 25300 = 3.3xN --> 25300 / 3.3 = N. The video used a different order of operations to complete the same task; they skipped the equation gymnastics and used the following logic: dividing 253 by 3.3 gives you 1% of the total family expenditure, then multiplying by 100 will give you 100% of the expenditure. Rewriting this would like: 253/3.3=N/100 --> 76.666 = N/100 --> 76.666 x 100 = N --> 7666.6 = N I prefer my method because I can fill in the gaps with the data that I KNOW and the data that I WANT to find, but I hoped this explanation helped people who were struggling with question 2.

Thanks a lot Sister

Your method takes way too long, remember these are timed tests.

+hotcupofsoup loooooooool

+hotcupofsoup When you calculate a percentage of some number, you're essentially calculating a fraction of the number. For example: 50% of 200 is 100, in other words, 1/2 of 200 is 100. In the above video, we are dealing with an increase in profits so calculating like above will only give how much the price increased/decreased by and not the end price. So to find the profit after the 13% increase, It is the fraction plus the original amount so 13% + 100% = 113%=1.13. Hope that helps and I didn't confuse you.

+Mit Prem That was a very thorough explanation, thank you.

mit prem thank you so much !!!!!!!!!!!!!!!!!!!! i was wondering about that!!!!!!!!!!!!!!! so if you have increased profit you need to do it for example 100 % 13 % = 113 % !!!!!!!!!!!!!! But if you have decreasion is just normal ...

Because an increase in 15% equates to multiplying the value by itself, and then a further 15%. You can break this down to multiplying by itself (1) and 15% (0.15). Why 0.15? Because 15% = 15 PER CENT = 15/100 = 0.15 Combine those actions and multiply the value by 1.15.

Thanks!

multiplying by 1.15 is confusing. there's a simple way to explain this. ''15% increase'' means add 15% of the original number to the number. 15% decrease means reduce 15% of the original number from the number.

Zadok Doye I don't understand how it's confusing. It's simple mathematics and it makes intuitive sense.

This is the formula for an increase in a percentage : New Value = (1+increase) x (original amount) So, in your case: New value = (1+ 0.15) x220= 253 P.S always change 15% to 0.15 because easier to calculate.

nope

Sameeee

This is the formula for an increase in a percentage : New Value = (1+increase) x (original amount) So, in your case: New value = (1+ 0.15) x220= 253

nashattar singh If you had bought 24, you would be left with 0.667 unaccounted for.

+walterrodney nagumo , he meant 15% increase of 220 which is 1.15*220=253, another way to think of it is if its increasing by 15% then you do 15% of original value which is 15*220=33 so if it's increasing by 15% then the new value is the original 220 plus the 33= 253. Hope that makes sense, its the same thing but just quicker to do 1.15

+Moira Mukwawaya 100%+15%=115% which is 1.15 :)

+walterrodney nagumo multiplying it by 1.15 saves you time from adding it later basically. your way works, but that way is must faster. so if they ask you that 'X' got an increase of 30% from the original price of 150, then what you do is '1.3 x 150 = 195'. If you use your way then its: '30/100 = 0.3/ 0.3 x 150 = 45/ 45 + 150 = 195' see, its basically the same result, just less working out and less time consuming :)

quite helpful explanation

Its not the math that is hard but rather the time constrain. And if the Chinese are so smart, perhaps they should have spend some time learning basic English which is the world's universal language instead of practicing these pointless tests that AI could solve.

Max Be careful different companies such as SHL and Kenexa have unique ways of structuring their questions. It’s better to prepare for a specific style of questions/set of conditions rather than random questions from the internet. Fundamentally you will need to be familiar with ratios, percentages etc. My latest video explains how to deal with SHL/Kenexa type numeric problems

Even worse he gets the wrong answer at the end. He had it re-dubbed to "C"

I hope not... I'm really bad at maths ..

Yes, absolutely.

Depends on what job you are applying for? if the job involves a lot of maths then I guess yes.

I'm applying for a marketing co-op i really hope they don't take maths extremly serious :^(

Fingers crossed bud!

Sheenamarie Zabala %/100 = dec Eg: 15/100 = 0.15 :. 15% as a decimal is 0.15, 29.34% is 0.2934 and 0.00486% is 0.0000486. OK?

Think of 100% as being a multiple of 1. E.G, 100% of 2 is 2, so equally, 2x1equals 2. It’s also possible to think of the percentage as being shifted to the left two decimal places, e.g 145% translates to 1.45, 635% to 6.35 etc.

God help me, I have numerical, verbal and abstract assessment online on Tuesday

how do you freeze the time?

I thought 13% as a decimal is 0.13....? Why so consfusing D:

Yes but it's value increases, so it has to be 13% bigger. So 100% of it's value + 13%. If you multiple only by 0,13, that will mean that it's value decreases 87%.

@@alekozlowska can you do shl test properly?

John is amazing hes my maths teacher

You do realize that by the time you might need that knowledge, it's already been way out of your head? You get good at math by practicing, if you are not practicing math 8-9 years later, then the knowledge you had at 14/15/16 years etc. is not readily accessible. These type of questions I believe for a position that already requires you to have math skills is fine, but I've had job offers that had no relation to these type of questionnaires and the type of job you actually performed. A lot of the times people just want to get overqualified people for the job with low self esteem. Actually doing the job makes you better at it, unless we're talking about risky jobs, like being a surgeon which you won't be able to get, unless you are a highly trained specialist already.

If it's 0.5 or higher you round up

Also 24 is not enough. You need a minimum of 25
