"She can make changes and receive three-tenths of the missing points back".

The question does not tell you what the max score is - only that she receives 65 points so you don't know how many 'missing' points there are.

Do you assume that this is 65 out of 100?

If not then you cannot do the question

Answer 11

suppose that there are 35 'missing points'

she can get back "3 tenths" of these each time

so what is the ratio for the series?
