Definition

更改, 更换, and 更正 all are Verbs, which means [change; alter; replace; make corrections].

Example

更正 is used to change or alter the mistakes or improper content in language, resolutions, regulations, etc; to replace the mistaken content with the correct one.
1) In example ① 更正启事 is an idiomatic collocation.

2) In example ② if 更改 is used instead, the meaning of "using the correct one to replace the mistaken one" would be lost, so it is not suitable.

3) In example ③ since it is not stated that 200元 is a mistake, so 更改 can be used instead, but the stress is different.

4) None of the three can use 更换.
