Time and Work
- If a person can do a work in x days, then work done by him in 1 day is $\frac 1x$
- If a person can do i/n units of work per day, then he can finish the work in n days.
- If A is n times more efficient than B, then A takes $\frac{1}{n}$th of the time taken by B to complete the same amount of work.
- To complete the same amount of work, more men will take less time and fewer men will take more time.
- m1 x d1 x h1 = m2 x d2 x h2
- If the amount of work increases then in the same duration the number of men required to complete the work increases
- If A takes x days to complete a work and B takes y days to complete the same work, then A and B together take $\frac{xy}{x+y}$ days.
