Question

A garrison has provision for 630 men to last 25 days in order to have the same food to last 30 day how many men must be transferred to another garrison ​

Answer 1

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.

Thank you.
