Answer 2

Answer:

The provision is for 20 days.

Step-by-step explanation:

Given : A garrison of 1200 men has provisions for 36 days. after 6 days, 400 men left.

To find : How long will the provisions last now?

Solution :

Let the provision is for x days

Total number of men = 1200

From which 400 men left.

Number of men left is 1200-400=800

For 1200 men provision is 36 days.

After 6 days,

Number of days 36-6=30

The provisions last now is

$x=\frac{30\times 800}{1200}$

$x=20$

The provision is for 20 days.
