The time taken for a particular operation for operator X in the Process Division of a manufacturing concern on three different counts was 24, 22 and 27 minutes while that of operator Y was 20, 23 and 26 minutes. It has been ascertained that the rating of ‘X’ is 70/60 and that of ‘Y’ is 55/60. Allowance for fatigue, personal needs are assumed at 15 per cent.
