Worker A completes a task in 8 days and worker B completes the same task in 10 days. If both A and B work together, in how many days they will complete the task? |

Answer» Answer: both will complete the WHOLE TASK in 40/9 Step-by-step explanation: WORKER A completes the task in 8 days. So in one day he will complete 1/8 part of the task. So, A's one day work =1/8 Similarly, B's one day work =1/10 ∴ (A+B)'s one day work =1/9 + 1/10 = 9/40 9/40 of the task is completed in one day so both will complete the whole task in 40/9 |
