7 men can complete a work in 12 days. They started the work and after 5 days two men left. In how many days will the work be completed by the remaining men?
Answers
Seven men can complete the work in 12 days
TOTAL WORK =7×12= 84 parts
Up to 5 days, all of them worked together
So, work completed =5×7= 35 parts
Remaining work = 49 parts
As 2 men left, so there are 5 men to complete the remaining task.
So, TIME TAKEN = 9.8 days
Given,
The number of men = 7.
The number of days 7men take = 12days.
The number of people left = 2.
To Find,
The number of remaining days to complete the work.
Solution,
Given that,
7 men finish the job in 12 days.
Let's take, the total work done = 12 * 7
84.
The work done by one man in a day =7unit
therefore,
Work done in first 5 days by 7men = 5*7
35unit.
After 5 days 2men left.
The work to be done in 7days = 84 - 35
49unit.
Therefore,
Let's find the total days to complete the job =
work/number of men
49/5
9.8days.
Hence, 9.8days are needed to complete the remaining work by 5men.
