To find the standard time (ST), we need to calculate the average time taken by the employee to attach a watch to a wristband.

Average time taken = (11+12+10+13+9)/5
= 11 seconds

Since the employee worked 20% faster than average, we need to calculate the time taken if the employee worked at an average pace.

Average time taken by employee = 11 seconds
Time taken at average pace = (11/1.2) = 9.17 seconds

Now, we need to add the allowance of 20% of job time:

Allowance = 20% of (11/1.2)
= 1.83 seconds

ST = Time taken at average pace + Allowance
= 9.17 + 1.83
= 11 seconds

Therefore, the standard time (ST) for this task is 11 seconds. The closest option is D (28.8 seconds) but this is not the correct answer.
