You can get at most 20% wrong. 20% of 16 is 16*20/100 = 3.2 Since you cannot get 0.2 questions wrong, the maximum possible is 3 questions.
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.
The answer depends on whether or not there are penalties (negative marks) for wrong answers. If not, then the answer is 30.
