Step-by-step explanation:
Let x be the number of men required to dig a trench of 27 meter.
Number of men11 x Length ( in m ) 643=42727Since, the length of the trench and the number of men are in direct variation, we have:
⇒ x11=2727/4
⇒ 11×27=x×427
⇒ x=2711×27×4
⇒ x=44
∴ 44 men will be required to dig a trench of 27meter.
