   aAn operator was kept under observation for five days. He was found working on 400 Occasions and abstaining idle 100 times. He produced 100 jobs during these days. The observation per day was five hours only and the total number of observations were 500. Take 130 as the performance rating for the operator and 30 percent allowance. Calculate the standard time.
   How to answer

   • Calculate proportion working p = 400/500 = 0.8
   • Total observed time = 5 days x 5 hours = 25 hours, effective working time
   • Normal time = observed time x rating / 100 / jobs produced
   • Standard time = normal time x (1 + allowance 0.30)
