Freshers may be looking at entry-level jobs, and in the absence of experience, you may not be able to put a number on your remuneration. By researching the salary ranges of various positions, you can get an idea of your compensation. Rather than giving a fixed answer, leave room for negotiation later. One way to do this is to say that you will accept the latest industry standards.
Example: “Since I am just beginning my career, I cannot give you a particular figure as my take-home salary, but I am eager to join a great brand like yours where I can get plenty of opportunities to sharpen my skills and further my career. At this point, I would say yes to the market package for beginners. Can you tell me what someone with the same experience level and job responsibilities receives at your company?”
