A contractor engaged 360 men to construct a road in 28 days due to emergency he had to finish the work extra men would be required to finish the work in time
Answers
Let's solve it by two methods.
Unitary Method :
If 360 men can construct a road in 28 days.
Then, in one day 360 × 28 men can construct a road.
And in 7 days 360 × 28/7 men can construct a road.
That is, 360 × 4 = 1440 men.
So, To complete complete the work on time the total men required are = 1440 - 360 = 1080 men.
Proportional method :
Let the number of men that will complete the task in 28 days be x.
This is an indirect proportion.
So, x/28=360/7
So, x = (360 × 28)/7
So, x = 1440 men.
Hence, the total men requiredto complete the task of constructing the road in 28 days is= 1440 - 360 = 1080 men.
Given:
A contractor engaged 360 men to construct a rod in 28 days, Due to emergency he had to fish work extra men would be required to finish the work in India.
Find:
Find how much extra workers would be required to finish in time.
Calculations:
Using proportional method:
Let "y" be number of men in 28 days.
Therefore, the number of extra men would be required to finish the work in time = 1440.
