Answer 2

Answer:

17.5 Hours

Step-by-step explanation:

Since, two administrative assistants can do a job in 20 hours.

Use of the computer cuts the time by 1/8.

So, use of computer cuts the time by$\frac{1`}{8} \times 20 hours$

which will be equal to 2.5 hours.

So, the total time taken by them with the use of computer will be 17.5 hours
