Answer:
8 days
Explanation:
no of men no of days
4 6
3 let be x
there is indirect variation
4/3=6/x
since it is in indirect variation do the reciprocal of any one fraction among these two fractions
4/3=x/6
do cross multiplicatin
3*x=6*4
x=24/3
x=8
therefore it take 8 days to complete the same work by 3 men.
