In a row of 15 students all facing north, what is J's position from the right end? Statement I: K is 4th from the left end and J is 6th to the right of K. Statement II: J stands somewhere to the right of the middle student. Which statement(s) is/are sufficient?

Question

Accepted Answer

Statement I alone is sufficient but Statement II alone is not. From I, J is at 4 + 6 = 10th from the left, i.e. 15 - 10 + 1 = 6th from the right. II gives only a range, not an exact position.
