Calculated multiquestions proposal

Working on it now. If you have ideas - you are welcome! General idea is: We have general set of variables and need to ask many questions related with some theory and this set of variables.

Now I'm working about questions for financial field. Which has now up to 20 variables and up to 10 questions.

But for example could be Geometry field, Right circular cone which has variables such as r(base radius), h(height), $\theta$(aperture)

And many questions could be such as:

1. Calculate slant height s? (Formula $s={\sqrt {r^{2}+h^{2}}}$ )

2. Calculate volume V? (Formula $V=1/3\cdot \pi \cdot r^{2}\cdot h$ )

3. Calculate surface area S? (Formula $S={\sqrt {\pi \cdot r\cdot s}}$ ) (depends on 1 question)

Seems that there is exist solution by Nicolas Dunand named Question Type: Multinumerical [1] but does not work in my case.
