Answer 2

Answer:

10 days

Step-by-step explanation:

Given :1000 men can do a job in 12 days

To Find : In how many days will 1200 men do this job? ​

Solution:

1000 men can do a job in 12 days

Let x be the number of days to do the job by 1200 men.

So, A.T.Q

$1000 \times  12 = 1200 \times x$

$\frac{1000 \times  12}{1200} =x$

$\frac{12000}{1200} =x$

$\frac{120}{12} =x$

$10 =x$

So 1200 men will take 10 days .

Hence 1200 men will do this job in 10 days.
