Quizplus · Accepted Answer

Performance rate = (Units produced / Observed time) x 100%
120% = (40 / 0.5) x 100%
Observed time = 0.5 hours = 30 minutes (given)
So, Units produced in 1 hour = 40 x (1 / 0.5) = 80 units
Allowance = 20% of the standard time = 0.2 x Standard time
Therefore, 1.2 x Standard time = (60 minutes / 80 units) x 100 units = 75 seconds
Standard time = 75 / 72 = 1.04 minutes (approx.)
Considering the available options, the closest answer is C) 1.00 minutes.
