If all the 20 questions had been answered correctly, you would have scored a total of 200 marks. Since you scored 125 marks, you have lost 75 marks.
Now, what you have to do is subtract 15 marks from 200 for every wrong answer. This is because you have to deduct 10 marks for not scoring in that question and 5 marks for answering it wrong.
15 * 5 = 75
Therefore, you answered 5 questions wrong.
