11 men can dig -metre-long trench in one day. How many men should be employed for digging 27-metre-long trench of the same type in one day?

More the length of the trench, more will be the no. of men required to finish it in a day. So it is a direct proportion.

6 m = m

Let the no. of men be x,

⇒ × x = 27 × 11

⇒ x = = 44 men
