    5 MARKS QUESTIONS DEFINITELY FOR IBPS PO PRELIM EXAMS     

Directions (Q. 1-5): Two equations (I) and (II) are given in each question. On the basis of these equations you have to decide the relation between ‘x’ and ‘y’ and give answer.

	(1)	if x > y	(2)	if x < y	(3) if x   y
	(4)	if x  y	(5)	if x = y or no relation can be established between ‘x’ and ‘y’.
