$8$ $8$ workers will finish the job in $2$ $2$ days.

Explanation:

Let the number of workers be $w$ $w$ and days reqired to finish a job is $d$ $d$ . Then $w prop 1/d or w = k* 1/d or w*d= k ; w=2 , d=8 :. k=2*8=16 :.w*d=16$ . [k is constant]. Hence the equation for job is $w*d=16 ; w=8, d=? :. d=16/w=16/8=2$ days.
