Solution :
------------------
Let the required number of days be x.
_______________________
Number of men | 28 | 14 |
-----------------------------------------------
Number of days | 8 | x |
_________________________
Cleary, more men will take less days.
So, it is a case of inverse proportion.
•°• 28 × 8 = 14 × x
=> 28 × 8 = 14x
=> x = 28 × 8 / 14
=> x = 16
Hence , the required number of days is 16.
