A job has a normal time of 12 minutes a performance rating of .80, and an allownmce factor of 20 percent of job time. The standard time for this job in minutes is:
A. 11.52
b. 12
c. 14.4
d. 15
c. 14.4
To determine the standard time for a job, we need to multiply the normal time by the performance rating and add the allowance factor.
Given:
Normal time = 12 minutes
Performance rating = 0.80
Allowance factor = 20% of job time = 0.20
Step 1: Multiply the normal time by the performance rating:
Standard time = 12 minutes * 0.80 = 9.6 minutes
Step 2: Add the allowance factor to the standard time:
Standard time = 9.6 minutes + (9.6 minutes * 0.20) = 9.6 minutes + 1.92 minutes = 11.52 minutes
Therefore, the standard time for this job is 11.52 minutes.
Answer: A. 11.52
To find the standard time for this job, we need to use the formula:
Standard Time = Normal Time x Performance Rating x (1 + Allowance Factor)
Given the values:
Normal Time = 12 minutes
Performance Rating = 0.80
Allowance Factor = 20% = 0.20
Substituting these values into the formula, we have:
Standard Time = 12 minutes x 0.80 x (1 + 0.20)
Simplifying the expression inside the brackets:
Standard Time = 12 minutes x 0.80 x 1.20
Now, we can multiply the values:
Standard Time = 11.52 minutes
Therefore, the correct answer is A. 11.52.
