How many people are in room A ?
(1) A total of 15 different pairs of people can be selected from the people in room A .
(2) If there were one fewer person in room A , a total of 10 different pairs of people could be selected from room A .
The answer can be D or E. Each statement is sufficient to answer the qs, but the answers are different for both of them , for the first its 30 and second its 21 , So shud it be D or E then ?
If both the statements are individually sufficient to answer the question, In any DS question the answer should be D.
It does not matter if the answers are same or different.
