20 workers are needed to carry out the work in 15 days.
As 30 is the double of 15 the number of workers will reduce by half.
Therefore, 10 workers are needed to carry out the work in 30 days.
This can also be done by unitary method—
20 workers—->15 days
30 workers 20/30x15days=10 days
As 30 is the double of 15 the number of workers will reduce by half.
