Question

Six men can build a 150m in 4 hours wall how many man can build 200m wall in 4 hours

Answer 1

Answer:

The number of men who can build 200 m wall in 4 hours is 20.

Step-by-step explanation:

Given as :

6 men can build a 150 m wall in 10 hours.

Let x men can build a 200 m wall in 4 hours.

According to question

Men x days. = Constant

Work

i.e

$\frac{m1 \times d1}{w1} = \frac{m2 \times d2}{w2}$

Or

$\frac{6 \times 10}{150} = \frac{x \times 4}{200}$

Or, 6 × 10 × 200 = x x 4 x 150

Or, 12000 = 600 x

.. X =

$\frac{12000}{600}$

i.e x = 20

So, The number of men = 20

Hence, The number of men who can build 200 m wall in 4 hours is 20. Answer
