I think here the answer to 2nd question is incorrect. The correct answer should be 200% because the value is 3 times i.e. from 10 to 30, hence the increase is of 200% and not 300%

Your reasoning is off.

The question isn’t asking how much more 30 is than 10 (which would be a 200% increase). It’s asking what percent of 10 is 30.

So the correct calculation is:

30/10 = 3, or 300% of 10.

That’s why the correct answer is 300%, not 200%.
