1. M_{1}D_{1}W_{2 } =
M_{2}D_{2}W_{1} (M-man, D-Day, W-Work).

2. If A can do a piece of work in x days, then

A’s 1 day work = 1/x.

3. If A’s 1-day work = 1/x, then A can finish a piece of work in x days.

4. If A is X times as good a workman as B then:

Ratio of
work done by A and B =** X
: 1**

Ratio of
time taken by A and B to ﬁnish a work = *1 : X.*

5*.*If** A **can do a piece of work in **x
days **and **B** can do it in **y days** then A and B working
together will do the same work in **xy/(x+y) **days.

6. If **A and B **together can do a piece
of work in **Y days** and A can do it in **X days** then B working
