Hi Pooja!This is Neeraj Atluri.Simple way to answer these questions are
Ram and Sita work together and complete work in 30 days=>daily work done by them is 1/30;
Ram alone work=10 days=>per day work is 1/10;
Ram +Sita=1/30
1/10+Sita=1/30
Sita=1/30-1/10;
Sita= -1/15;
As you got the answer in negetive,Your question is not so appropriate because "the task completion days induvidual should be" >"Task completion days when they work as group".But according to your question it is vice versa.So your question is not so appropriate.
