Question

In a camp food is sufficient for 700 soldier for 45 days if half of soldiers leave after 10days then find out for how manydays more the food last

Answer 1

In a camp food is sufficient for 700 soldier for 45 days,

700 men x 45 days = 31500 (total food)

This is your standard equation for total food.

Now, for 10 days, 700 men will eat:

10 x 700 = 7000

Food left = 31500 - 24500.

After 10 days men left at the camp,

Men left = 700/2 = 350

Again, move to the same formula -

350 men x No. of days = 24500 (total food)

No. Of days = 24500/350

= 70 Days
