If A complete a work in x days and B does the same work in y days. In how many days together A and B will complete that work? |
$\frac{x y}{x-y}$ days $\frac{x+y}{x y}$ days $\frac{x y}{x+y}$ days $\frac{x-y}{x y}$ days |
$\frac{x y}{x+y}$ days |
Total work = Efficiency × Time Total efficiency of both A & B = x + y Total work = xy Total time taken = \(\frac{xy}{x + y}\) The correct answer is Option (3) → $\frac{x y}{x+y}$ days |
