Question

Three persons, working full day, can finish a job in 10 days. How many days will it take to finish the same job if one of them can only work half day?

Answer 1

It would take 20 days

Since 240 hrs is 10 days

If half day only 12 hrs perday

12 × 20 =240

Answer 2

12 days will need to finish the same job.

Step-by-step explanation:

Let x be the total amount of work to be completed

Given : 3 workers can complete x work in 10 days

∴ Amount of work done by 1 worker in 1 day is,

$\\ \text{Workdone} = \frac{\text{x}}{30}$

If one worker can work only half day then amount of work done by him is,

$\text{Total amount of work done} = \frac{\text{x}}{30} + \frac{\text{x}}{30} + \frac{\text{x}}{60}$

$\text{Total amount of work done} = \frac{\text{x}}{12}$

Hence 12 days is required to finish the same job if one worker work only half day.
