Question 396307
 
 To complete the work in 8 days require 2 persons

so, to complete in 1 days .............2*8 = 16  persons

 to complete in 6 days.................2*8/6 = 2.66 

it means 3 persons are required to complete the work in 6 days..


so, only one extra person need to hire.



work will complete in  16/3 = 5 + 1/3 days
