I'm bored. Give me a challenging maths problem to work on.

I hate lift questions haha

You have to round downwards because you are using the maximum values to work out X. So the number you get, such as 8.5, is the absolute maximum number of people you can have.

Since you can't have 8.5 people, the maximum, you can only have 8 people.
If you have 9 people the lift will break because it can't hold that force, it can only hold 8.5.

Assuming if 8.5 was the correct answer, of course.

+ the answer for your second question should be 1, I can't see why not.

OK thank you for the help

Try a STEP paper. Nothing is more challenging

It makes a change to have a female (one of those) contribute. STEP, unfortunately, is far too hard for what a-level maths course teaches (students typically score less than 40%, meaning they cannot manage even half of the paper, and these are future maths students..)

when solving these problems, you're not meant to see the answer immediately. The trick is to analyse it for many minutes first.

Idk what is challenging for you

Here's one that's probably too easy, prove that n^3 - n is divisible by 6 for n a natural number

Was that on an FP2 paper somewhere? I'm sure I have done this before!

I am disgusted that a male would say that of a mathematics thread. Please leave.
