I got 99 too! I quite enjoyed some holiday maths!

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

Why is it not £179.80??? I cannot understand why I got it wrong.

Am I mis-reading the question?

Consider an item that costs £100 + VAT. With VAT at 20%, the price including VAT is £120.

Now, if I told you that the price including VAT was £120 and you used the same method to calculate how much the VAT had been, you would get £24. Something's wrong, isn't it.

It's probably better if I let you figure out the rest for yourself. But here's shortcut: try dividing by 6.

98% too. Quite happy with that but the question about the coach is ambiguous.
"A coach can take 52 passengers. For every 6 children there needs to be at least one adult. What is the maximum number of children on the coach? Answers are 42,44,45 or 49."
The driver is an adult so 45 kids or the driver isn't a passenger so 44 kids?

6 children + 1 adult = 7 seats occupied.

x 7

42 children + 7 adults = 49 seats occupied.

You are suggesting that the coach driver can supervise at the same time as driving, to fill the remaining 3 seats with children, so 45 children. I'm not convinced on this, as who would supervise these extra 3 children when the driver is not watching them. Think you are over thinking this, but I can see the ambiguity.

I got 89, took me back to my schooldays. Made me realise how rusty my mental arithmetic has got

Bonus question:
If Pinkshoes says she got the VAT question wrong, how many people will repeatedly post the answer over and over...and over.

Sorry, meant to say that 42 was my first answer that was wrong. It must be 44 or 45 ….

What a lot of geeks read moneysavingexpert. No wonder it's difficult to overcharge us.... I got 100 too.

I can report a 98.
Got careless with one answer and disagree with them over the other.
