Question

A military camp has provision for 630 men to last for 25 days.Howmany men must be transfeered to another camp so that the food last for 30 days?

Answer 1

No. of days | 25 days | 30 days

No. of men | 630men| x men

No. of days and the no. of men are inversely proportional...

25×630 = 30× 'x'

x = 25 × 630 / 30

x = 25 × 63 / 3

x = 25 × 21

x = 525 men ...

630 - 525 = 105 men must be transferred to make the food last for 30 day...
