Answer:
Let x be the number of men required to dig a trench of 27 meter.
Number of men 11 x
Length ( in m ) 6
4
3
=
4
27
27
Since, the length of the trench and the number of men are in direct variation, we have:
⇒ 11/x = 27/4/27
⇒ 11×27=x× 27/4
⇒ x= 11×27×4/27
⇒ x=44
∴ 44 men will be required to dig a trench of 27 meter.
