Question

Through Maths Eye 3 workers can complete a task in in 10 days by working 8hours each day if one of them has left the job.how many hours each day should other worker do the job if the task is to be completed in 12 days.​

Answer 1

Step-by-step explanation:

Let us assume that total amount of work required is X.

So 3 workers in 10 days can do X.

Hence 1 worker in 1 day can do X/30.

Now since 1 of them can only work half day, he/she will be able to do only X/60.

So total work received from 3 people in 1 day is:

X/30 + X/30 + X/60 = X/12
