A can finish work in X days.

B can finish work in Y days.


Both can finish in Z days = (X*Y) / (X+Y).


Problems Type 2:

Both A and B together can do work in T days.

A can do this work in X days.


then, B can do it in Y days = (X*T) / (X-T)


Problems Type 3:

A can finish work in X days.

B can finish work in Y days.

C can finish work in Z days.


Together they can do work in T days = (X*Y*Z)/ [(X*Y)+(Y*Z)+(X*Z)]


Problems Type 4:

A can finish work in X days.

B can finish work in Y days.


A*X = B*Y

Y = (A*X) / B


Problems Type 5:

A can finish work in X days.

B can finish work in Y days.


A left work after P days then B need to work Q days

Q = [(X - P) / X ] * Y

Problems Type 6:
