For Q25 (Resolved)
The answer is D
I had a look at the solutions and it shows for e.g.
13.14/125= 10.5p/m
I don't get how they got the 125.

I was going to start answering but I'll be here all morning.

For the original first one, its D is 20.94 which seems to be the cheapest. You could approximate in terms of 25m length roll price, at that looks like the best one for me. For 13.14, I'd have divided by 6 to get the equivalent 25m length roll price.

Good luck with (all) the others. I'd really suggest splitting them up into separate posts.

Advice noted and Q25 makes sense now :smile:
