Question

a Garrison of 1200 men has provisions for 15 days how long will the provisions last if the Garrison be increased by 600 men?​

Answer 1

Given,

The garrison of 1200 men has provisions for 15 days.

Later, 600 men joined the garrison.

To find,

The number of days that the provisions will last after joining of new 600 men.

Solution,

We can solve this mathematical problem by using the normal arithmetical method.

Number of men after joining = 1200+600 = 1800

So,

For 1200 men = 15 days

For 1 man = 15×1200 days

For 1800 men = 15×1200/1800 = 10 days

[The two terms are inversely proportional to each other.]

Hence,the provisions will last for 10 days.

Answer 2

Step-by-step explanation:

numbers of men after joining the garrison:- 1200+600=1800

for 1200 men- 15 days

for 1 men - 15*1200

for 1800 men - 15*1200/1800= 10 days
