please write the answer immediatly​

Answer 1

Step-by-step explanation:

20*30 = 600 men-days.

2. 20*6 = 120 men-days

3. 600 - 120 = 480 men-days.

4. 20 - 8 = 12 men remained.

5. 480%2F12 = 40 days.

Answer. It will take 6 + 40 = 46 days to complete the job, counting from the very fist day

Answer 2

Answer:

46days

Step-by-step explanation:

In 30 days, a work can be done by 20 men

In 1 day, a work can be done by (20 ×30)men =600men

For the first 6days, the man-days =(20×6)

120

So,after 6 days 8 men fell sick.

No. of workers at present =(20-8)men

=12 men

let, d be the no. of days man will complete the remaining work.

BTP

120+12d=600

or, 12d=600-120

or, 12d=480

or, d=480/12

or, d=40

The workers will take total 40+6= 46days
