5 workers take 12 days to weed field
1 worker alone would take around 12× 5 = 60 days since he alone cant finish it earlier
and more over number of worker is inversely proportional to the no of days.
Thus 6 workers would take =60/6 = 10 days
And , 15 workers would take = 60/15=4 days.
Hope this is ur required answer.
