how many discussions we can answer in one day

now i have no time but i thought to do minimum 150 to 200.only thing is hard work

There is no limit to the amount of discussions one can answer in a day. However I can tell you that you will earn more for quality responses over quantity. That means that if you go around and answer 50 discussions with one liners, and I go around and respond to 25 with quality I most likely will earn more in a day than you. The reason is that mylot is looking for quality responses and discussions not quantity. Mylot encourages us through the guidelines to stay away from specific kids of discussions. Heed the advise as they do delete discussions, which means that all responses in those discussions are also deleted and earnings go down for responding to those discussions. Welcome to mylot, hope this helps for you to earn higher. If you should have further questions I'm happy to help! :)
