How good are you with numbers? Take the National Numeracy test

Your answer is simply 20% of the total price. You need to understand that the starting price (without VAT) needs to be considered as 100% so when the VAT is added you have 120%; so that the price with the VAT and divide by 1.2 and you get the price before VAT gas been added -

say the price was 200 before VAT - 20 % of that is 40 so total with VAT is 240

Now starting with the 240 divide by 1.2 and you will get 200, the price before VAT was added.

I hope you get it now!

99. made the stupidest mistake in the world using the wrong dataset for the "which quarter had lowest cost per project" - i swapped the primary and secondary y axis

Definitely wouldn't contend any of the other question answer validity - i can see where some were tricky and may catch you out if you don't pay attention though!

Got 100% twice. Site gave an error message just as I completed it first time, so I though it might have lost the lot and I resat the whole test.

The questions are not all the same every time, as comments have noted.

[I would be upset with myself to get any wrong - I teach Maths].

I got 98, but didn't see some of the questions being discussed here, so not everyone is being asked the same set.

I definitely got the "quality check" wrong (misread the question), but I disagree about the "IT incidents average" one. They don't say what the right answer is supposed to be, I said it was "mode". Since 15 is definitely the mode (3 occurences - all other values only have one), the only other possible correct answer is "median and mode". But there are 3 occurrences greater than 15 and only one below, so that can't be right ...

correct answer was definitely median and mode.

I got 87 out of 100. Really disappointed in myself!! Thought i'd get around 93-95 but it was harder than I thought.

I didn't use a calculator, but did use pen and paper to work stuff out. And didnt spend more than a couple of minutes on a question.

!!!!!! was the bike wheel circumference one about though?!?!

what caught you out?
you can work out radius given diameter. from there you can work out distance bike would travel each revolution of the wheel, so many revolutions it would take to achieve a specific distance.

I got 98. For the 2 that I "got wrong", I calculated the right answers but must have clicked on the wrong answer!

Hi pinkshoes

It's because you need to do a little formula:-

Price x 1.2 (20% markup) = £899

Therefore

Price = £899/1.2 = £749.17

20% of £749.17 is £149.83

So...

£749.17 Purchase Price
£149.83 VAT

---

£899 Total

20% VAT is s rip off :rotfl:

Hope this helps!

I have always had problems with this type of calculation. Doing it the long way around using a calculator the cost of the item is £749.16 and plus 20% vat £149.83 makes it £899. There is a logical way of doing this but I cannot remember how it is done. Just Googled it and it is so simple

Gross price divided by 1.2 = Net price

Price after tax divided by 1.2 = Price before tax

"I got wrong:
You buy a laptop that costs £899, including VAT at 20%. How much of the purchase price is VAT?"

Depending on how you read the question - 20% of purchase price is VAT

I scored 97, with 5 "incorrect" answers. 3 of these were definitely my mistakes. One (effectively, which city is 180 miles from London?) I cannot tell what the "right" answer is.

The last one, about how much the failure rate has decreased, I think the question is ambiguous. If the failure rate was 25% and is now 10%, is the decrease 15% (of the total number of tests) or 60% (=15/25) as a percentage of the number of failures. I answered 15% and was told this is wrong. Is this the question that Martin was also disgruntled about?
