1) Total wages = Wages of 1 day work × Total number of days

2) If P can do a piece of work in x days and Q can do the same work in y days, the ratio of their wages will be y : x. Then the wages earned by P and Q will be

$ \text"P's wages" = {\text"Total wages"}/{(x + y)} × y $

$ \text"Q's wages" = {\text"Total wages"}/{(x + y)} × x $

3) If P, Q and R can do a piece of work in x, y and z days respectively, the ratio of their wages will be yz : xz : xy. Then, wages earned by P, Q and R respectively will be

$ \text"P's wages" = {\text"Total wages"}/{(xy + yz + zx)} × yx $

$ \text"Q's wages" = {\text"Total wages"}/{(xy + yz + zx)} × xz $

$ \text"R's wages" = {\text"Total wages"}/{(xy + yz + zx)} × xy $

4) P can do a piece of work in x days. With the help of Q, P can do the same work in y days. If they get ₹ a for that work, then

$ \text"Share of P" = {ay}/{x}$

$ \text"Share of Q" = {a( x - y )}/{x}$

5) P, Q and R undertake to do a work for ₹ a. If together they do only $x/y$ of the work and rest is done by R alone, then

$ \text"Share of R" = a (1 - {x}/{y} ) $
