Model Questions for IBPS PO PRELIM Exam : Quantitative Aptitude Set-47

Directions: In each of the following questions, a number series is established if the positions of two out of the five marked numbers are interchanged. The position of the first marked numbers are interchanged. The position of the first unmarked number remains the same and it is the beginning of the series. The earlier of the two marked numbers who positions are interchanged is the answer. For example, if the interchange of the number marked (4) is required to establish the series, your answer is ‘1’. If it is not necessary to interchange the position of the numbers to establish the series, give ‘5’ as your answer. Remember that when the series is established, the numbers change from left to right (i.e., from the unmarked number to the last marked number) in a specific order.
