Question

15 men can dig a 20 m long trench in one day. How many men should be employed for digging 140 meters long trench of the same type in one day​

Answer 1

Answer: 105 men

Step-by-step explanation:

In one day

15 men can dig 20 m

let x men dig 140 m

Using Proportion:

x/15 = 140/20

x= (140 x 15)/20

x= (14 x 15)/2

x= 7 x 15

x=105

105 men can dig the trench in one day

Answer 2

Answer:

105 men should be employed for digging 140 meters long trench of the same type in one day​.

Step-by-step explanation:

Given:

It has been given that $15$ men can dig a $20m$ long trench in one day.

To find:

We have to find the number of men that should be employed for digging 140 meters long trench of the same type in one day​.

Solution:

Since, 15 men can dig 20 m in one day,

Let "x" number of men dig 140 m

By using the method of Proportionality:

$\frac{x}{15} =\frac{140}{20} \\x= \frac{140 \times 15}{20} \\x= \frac{14 \times 15}{2} \\x= 7 \times 15 \\x=105$

Final Answer:

Hence, 105 men should be employed for digging 140 meters long trench of the same type in one day​.
