Tip of the Day In Data Sufficiency questions only unique answer from a single statement is acceptable. If we have a quadratic equation where there are two distinct acceptable roots then the answer would not be unique. At the same time if both the roots are same or if one of the roots can be discarded then unique solution would be possible. Last year's Question of the day (20-May-11) If x and y are positive integers and 7x2 − 2xy + 3y2 = 27, what is the value of x?
