Question

There are 800 soldiers in an army camp. There is enough provision for them for 60 days. If 400 more soldiers join the camp how many days will the provision last

Answer 1

The provision can provide for 800 soldiers for 60 days

Find the number of days it can provide if there is only 1 soldier:

800 soldiers = 60 days

1 soldier = 60 x 800 = 48,000 days

Find the total number of soldiers now:

Total number of soldiers = 800 + 400 = 1200

Find the number of days it can provide for 1200 soldiers:

1 soldier = 48,000 days

1200 soldier = 48000 ÷ 1200 = 40 days

Answer: The provision can last for 40 days

Answer 2

Heyaa..☺️
.
Here's the answer-

800 soldiers - 60 days

800+400=1200 soildiers - x days
( Its a example of inverse proportion )

So, 800×60/1200

= 40 days
