175 man big a Canal 3150 long in 36 days how many men are required to dig a Canal 3900 long in 24 days

Answer 1

Answer:

325 men are required to dig a 3900 m long canal in 24 days

Step-by-step explanation:

If 175  men can dig a canal which is 3150 m long in 30 days

then,

canal digged in one day = $\frac{3150}{36}$ = 87.5m

canal digged in one day by one man= $\frac{87.5}{175}$ = 0.5m

therefore for 3900 m in 24 days

canal digged in day = $\frac{3900}{24}$ = 162.5 m

now

let the number of men required to dig a canal which is 3900 m long in 24 days be x

$\frac{162.5}{x}$=0.5

then by solving

x= $\frac{162.5}{0.5}$

x= 325 men

325 men are required to dig a 3900 m long canal in 24 days
