摘要：The major process in the education methodology is organizing and conducting the examination. Administration of the question paper setting is an important task in the objective-type examination system. While setting the objective type question paper, the highlighted problems are the lack of expertise, the time, and the questions redundancy. Generally, during the retrieval of records from an objective type question bank redundancy may occur even for the large size databank as well as smaller size databank. To solve this problem, a methodology is required to retrieve records from a database without redundancy. This paper discusses the impact of mid-square, mid-product and constant multiplier techniques for random number generation, to retrieve records from the question bank with minimal redundancy as far as possible. To retrieve records from a database, a modified approach is identified and applied to generate random numbers. Also, this paper justifies the role of suggested approach, which performs reasonably better than the actual techniques reported in the literature for records retrieval process even for a smaller size database.
