### Time and work

Time and work simultaneous performance involving the efficiency of an individual or a group and the time taken by them to complete a piece of work.

Important formula:-

• If A can do a piece of work in n days, then A’s one day’s work = 1/n
• If A’s one day’s work = 1/n, then A can finish the work in n days.
• If A is thrice as good a workman B, then

The ratio of work done by A and B = 3:1

The ratio of times taken by A and B to finish work = 1:3

• Total work = No of days * Efficiency.

Pipes and Cisterns Formula-

• Inlet: A pipe connected with a tank or a cistern or reservoir, that fills it, it is known as an inlet.
• Outlet: A pipe connected with a tank or a cistern or a reservoir, emptying it, it is known as an outlet.
• If a pipe can fill a tank in x hours, then the part filled in one hour = 1/x.
• If a pipe can empty a full tank in y hours, then the part emptied in 1 hour = 1/y.
• If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where y>x) then on opening both the pipes, the net part filled in one hour = (1/x – 1/y)
• If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where x>y), then on opening both the pipes, the net part emptied in one hour = (1/y -1/x).
