Answer 1

Answer:

Food will Last

18 Days

Step-by-step explanation:

there is provisions of food for 360 persons for 21 days

total food available for = 360 × 21 Man Days

= 7560 Man Days

 if 60 more men join then Men available  = 360 + 60 = 420 Persons

Food will last for  = 7560/420 = 18 Days

Total number of days food will last = 18 Days

Answer 2

18 days the provision will last.

Step-by-step explanation:

As given in the question that in a fort 360 men had provisions for 21 days.

We have to find how long will the provision last if 60 men join them.

Let the provision last is x.

Now, if 60 men join.

Total men = 360 + 60

                 = 420 men

According to the question,

$420\times x = 360\times21$

$x = \frac{7560}{420}$

x = 18 day

Therefore, 18 days the provision will last.
