E. None of these
D. 10 days​

Answer 1

Answer:

Let’s assume 1 Man does 1 part\day.

Seven men can complete the work in 12 days

TOTAL WORK =7×12= 84 parts

Up to 5 days, all of them worked together

So, work completed =5×7= 35 parts

Remaining work = 49 parts

As 2 men left, so there are 5 men to complete the remaining task.

So, TIME TAKEN =495= 9.8 Days

Thus, the remaining work will be completed in 9.8 Days (Answer)

Answer 2

Step-by-step explanation:

7 men = 12 days

1 man = 12/7

= 1 . 71 days

5 men = 1.71*5

= 8.55 days

They takes 8.55 days to complete a job
