TIME AND WORK

TIME AND WORK

1.
tA+B = (tA * tB)/tA


2.
tB = (tA * tA+B)/tA - (tA+B)


3.
tA+B+C =[ L/(L/tA) + (L/tB) + (L/tC) ]

		L  --->  L.C.M of tA,tB,tC.

4.
tC =[ L/(L/tA+B+C) - (L/tB) - tB) ]


5.If A+B, B+C, A+C are given then A+B+C=?

   (i)
tA+B+C = 2L/[ (L/tA+B) + (L/tB+C) + (L/tC+A) ]


   (ii)
tC = 2L/[ (L/tB+C) + (L/tC+A) + (L/tA+B) ]


   (iii)
tB = 2L/[ (L/tA+B) + (L/tB+C) + (L/tA+C) ]


6.
S1d1 = S2d2


7.
wA+B = [ (wA * wB)/(wA+wB) ]


8.Working alternatively,


2 * tA+B = 2 * [ (tA.tB)/(tA+tB) ]
