Time & Work

If A can do a piece of work in n days, then A’s 1 day’s work = 1/n.

If A’s 1 day’s work = 1/n, then A can finish the work in n days.

If A is thrice as good a workman as B, then:

Ratio of work done by A and B = 3 : 1,

Ratio of times taken by A & B to finish a work = 1 : 3

Pipes & Cisterns
