Calculate part of work done by each person each day. Calculate total part of work done in one part of time (in this case one day) by the total no. of persons. Then find out time required for 1 (whole) part of the work.[In this numerical, you have to calculate 4 part (as the question is 4 times).]
This process is applicable for most numericals of this type.
