e. 32 seconds.

Explanation:

The computation of the standard time is shown below:

= (Normal time) : (1 - allowance of percent of job time)

where,

Normal time = 20 seconds * 1.2 = 24 seconds

The 1.20 is come from 1 + 20%

And, the allowance of percent of job time is 25%

So, the standard time is

= (24 seconds) : (1 - 0.25)

= (24 seconds) : (0.75)

= 32 seconds
