Neco 2018 Data Processing Question 18
Practice objective / multiple choice question 18 from the 2018 Neco Data Processing examination.
During a batch data‑processing run, 1 500 records are input. In the first processing stage, 5 % of the records are flagged as erroneous and sent back for correction. After correction, 3 % of the original records are still erroneous and are discarded. The corrected records (those that were flagged) are then processed a second time; in this second processing stage, 2 % of the corrected records are again flagged for correction, and after this second correction 1 % of the original records are finally discarded. Assuming all flagged records are successfully corrected after each stage, how many records are finally stored at the end of the cycle?
