Answer 2

There are 600 additional army men that had joined the camp after 30 days.

Step-by-step explanation:

Number of men = 1400

Number of days = 40 days

After 30 days, some more army men join them and now the food lasts for only 7 more days.

So, we will use "Time and Work" to find the additional army men.

$1400\times (40-30)=x\times 7\\\\1400\times 10=x\times 7\\\\\dfrac{14000}{7}=x\\\\x=2000$

So, Additional men would be

$2000-1400=600$

Hence, there are 600 additional army men that had joined the camp after 30 days.
