It can be solved by simple unitary method
assuming constant efficiency
If 6 MEN make 540 LADOOS/hr
Then
1 MAN makes 90 Ladoos/hr
OR
90 LADOOS /hr /man
to make 900 LADOOS/hr
no. of MEN = 900/90 =10

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.***
This process is applicable for most numericals of this type.
***NOTE:
In this case calculate 900 parts.
