TIME AND WORK

TIME AND WORK

Then the general formula in the relationship of M1 D1 W2 = M2 D2 W1

  1. More men less days and conversely more days less men.
  2. More men more work and conversely more work men.
  3. More days more work and conversely more work days.

WORK & WAGES

Wages are distributed in proportion to the work done and in indirect (or inverse) proportion to the time taken by the individual.
There are two methods: – Eg. A can do a work in 6days and B can do the same work in 5 days. The contract for the work is Rs. 220. How much shall B get If both of them work together.
Methods I : –

PIPES AND CISTERNS

Pipes & Cisterns: These problems are almost the same as those of Time and work problems. Thus, if a pipe fills a tank in 6 hrs, then the pipe fills 1/6th of the tank in hour.
There is one difference that pipes & cisterns problems is that there are outlets as well as inlets. Thus, there are agents (the outlets) which perform negative work too. The rest of the process is almost similar.
Inlet
A pipe connected with a tank (or a cistern or a reservoir) is called an inlet, if it fills it.

Outlet
A pipe connected with a tank is called an outlet, if it empties it.
