Question 321072
In a camp of 4000 men, there were provisions of food for 190 days.
that's 4000*190 = 760,000 ration-days available
:
After 30 days 800 men went away to another place.
:
After 30 days, 4000*30 = 120000 ration-days consumed
760000 - 120000 = 640000 ration days remain
:
;
How many days will the rest of the food provide the remaining men?
:
Let d = no. of days
(4000-800)d = 640000
3200d = 640000
d = {{{640000/3200}}}
d = 200 more days
