A job has a normal time of 12 minutes, a performance rating of 0.80, and an allowance 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.
e. depends on the number of cycles observed.

Solution :

The standard time for doing a job in minutes is given by :

Standard time = Normal time + normal time x allowance factor.

Here, it is given that ,

Allowance factor = 20%

                            = 0.20

Normal time of doing a a job = 12 minutes.

Therefore,

Standard time = Normal time + normal time x allowance factor

Standard time = 12 + 12 x 0.20

                        = 12 + 2.4

                        = 14.4

Thus, the standard time for doing the job is 14.4 minutes.
