_______
4

Answer 2

Answer:

30 workers

Step-by-step explanation:

if 6 workers can complete a job in 20 days,

then they can do in 1 day =1/20 part of the work

If six workers can do 1/20 part,then 1 worker can do 1/120 part of the same work.

i.e. 1 worker can alone do the same work in 120 days.

If the same work has to be done in 4 days only,then a total of 30 workers are required.

Hope it helps you.
