Time and Person is inversely proportional , where if person increases ,time decreases. Formulas : If `A` completes work in `n` days , then the work completed in one day is 1/n th part of work. If `A` completes 1/n th work in one day, then total work completed in `n` days. Let us assume `A` completes the work in `n` days and `B` completes the work in `m` days .Let us take work as only one unit, the amount of work done in one day by `A` is 1/n similarly for `B` is 1/m. So in how many days the work is completed if they work together then ,A + B = 1/n + 1/m. Problem...
