Answer 2

Six labours will take 45 days to complete the task

Days taken by 18 labours to complete the task =  15 days.  (Given)

Thus,

Total man days needed to complete the task

= 18 × 15  

= 270 mandays

Now, time taken by 6 labours to complete the task -

= 270/6

= 45

Thus 6 labours will take 45 days to complete the task.
