Hello,
The plan of a plot is represented at a scale of 1:2000 on an A4 sheet, this plan is enlarged to A3 format, what scale is it now?

Uh, for me, the ratio always remains the same...
In one case, from A4 to A3, it increases (you multiply the measurement by 1.414 (approx)
And in the other, from A3 to A4, it decreases (you divide the measurement by 1.414 (approx)

In the inverse report, if we want to know measurements on an A3 sheet printed on A4 paper, we should obtain it by dividing the measurement by 58.5 (100-41.41) and multiplying the result by 100. If someone could confirm this hypothesis for me. Thank you in advance.
When you move from A4 to A3, you double the area, but you do not double the dimensions.
The enlargement ratio is therefore the ratio between the diagonal for A4 and the diagonal for A3, which is approximately 41.41%.
The new scale is the ratio between the new dimension on the A3 sheet and the actual size, which in your case is about 1/1414.
