Answer:

Productivity of clerical worker (fraction of job done in 1 hr) = x

Productivity of secretary (fraction of job done in 1 hr) = y

y = 4x

x*6hrs + y*6hrs = 1 (100% of work done)

6x + (4x)*6 = 1

30x = 1

x = 1/30

He can do 1/30th of the job in 1 hr. So it will take him 30 hrs to do 100% of the job.
