Answer 1

Answer:

25 days = Food for 630 men

30 days = x (Inverse variation)

30 * x = 630 * 25

x = 630 * 25/30

= 21 * 25

= 525 men.

630 - 525 = 105 men.

Therefore, 105 men must be transferred to another camp so that the food lasts for 30 days.

Answer 2

Answer:

According to the question 

25days=foodfor63men

30days=x

30×x=63×25

x=3063×25

≈53men

Hence,

=63−52.5men

=10.5

Hence 10.5 ≈  men must be transfered to another comp therefore the food lasts for 30 days.
