# Is there any questions similar to this in Maths? Never seen it before Watch

1. It's a fairly straightforward problem solving question.

How long is part B?

So then can we work out how heavy it is?
2. This is of a real exam paper. It's the first time I've seen a question like this but if it has come on once it can come on again.

and dude this isn't the only question that we've never come across before, there's a bunch more as you go through the paper.
4. Do you not understand the question? its quite easy really.

The length of part A is 5 metres, and this weighs 8kg

This means that each metre of the cable weighs 8/5 = 1.6

As part A is 5 metres, and the whole thing is 16 metres, part B must be 11 metres long

11 x 1.6 = 17.6 kg

Not quite sure what topic it comes under, but the question does not seem unreasonable
5. Well if the parts come from the same cable then the weight will increase in proportion to the length.

So if part A is 5m, then part B must be 11m.

If part A weighs 5m, that means every 1 meter weighs 1.6kg - you divide the 8kg by 5.

Therefore, 11m multiplied by 1.6 gives us 17.6kg

It's simple maths put into a wordy question.

The thing is, you can't expect the same question to come up every time. It's an exam and is meant to be challenging to test your true ability especially with maths, there are no two same questions which will come up, it's how you use your skills and knowledge and how you apply it to the problem. Otherwise, it'll be too easy and everyone will be getting A* and that isn't right!!
6. Yep, I had this question in my mocks. I think it came up on one of the November 2015 modular papers.
7. This type of question I would use Enlargement Scale Factor.

So (11/5)X8 which makes 17.6 kg.

8. Am I the only one annoyed that they used 'kg' as the unit for weight?

whats wrong with that
10. (Original post by life.of.pablo)
whats wrong with that
weight is a force so it is measured in newtons (N)
mass is measured in kg
11. What is a predicted paper?

What is a predicted paper?
It is what they're guessing might come up and then you can do that predicted paper based on those guesses as practice

Basically a practice paper

Basically a practice paper
Yeah based on the guesses. They guess by seeing which topics come up a lot and then make practice paper

I'm not gonna lose any sleep over it
17. Does anyone have the mark scheme for this paper?
