To calculate the standard time, we need to first calculate the normal time (observed time without allowance), which is the average of the total times for each element:

Normal time = (39.72 + 25.08 + 30.60 + 22.14 + 15.12) / 20
Normal time = 2.8135 minutes

Next, we calculate the standard time by adding the allowance factor to the normal time:

Standard time = Normal time * (1 + Allowance factor)
Standard time = 2.8135 * (1 + 0.20)
Standard time = 3.3762 minutes

Therefore, the answer is B) 12.10 minutes (since there are 20 cycles of the job, we simply multiply the standard time by 20 to get the total time for the job).
