Question

70 men can complete a wall of 150 Meter length in 12 days .how many men will complete the walls of length 600 Meter in 30 days.

Answer 1

((600/150)*70)*(12/30)= 120 mens

Answer 2

Answer: There are 112 men who can complete a wall of 600 m in 30 days.

Step-by-step explanation:

Since we have given that

Number of men = 70

Number of days to complete a wall of length 150 m = 12

So, if the length of wall = 600 m

Number of days = 30

We need to find the number of men to complete it .

As we know the formula for "Time and work":

$\frac{M_1\times D_1}{W_1}=\frac{M_2\times D_2}{W_2}\\\\\frac{70\times 12}{150}=\frac{M\times 30}{600}\\\\M=\frac{70\times 12\times 600}{150\times 30}\\\\M=112$

Hence, there are 112 men who can complete a wall of 600 m in 30 days.
