Answer 1

Step-by-step explanation:

No. of men who had the provision=1200

400 more men join the fort.

Total men in the fort=1200+400=1600.

Now, 1200 men eat food in 20 days.  

1 man eats food = 1200×20 days.

So, 1600 men eat it =1200×20/1600

=24000/1600  

=240/16

=15 days

Hope it helps

Answer 2

Answer: 3/20

Step-by-step explanation:

if you take 1200 is equal to 20 as 1200=20 plus you have been told that 400 if for only a day  so its 1200=20

                                     400=1?          $\frac{1200}{8000}$
