Question

120 men had food provision for 200 days. after 5 days, 30 men left that place. how long will tha remaining food last

Answer 1

ANS: provision available for 120 men for200 days

total provision can be consumed by 1 man = 120 *200 = 24000 days

Since , after 5 days 30 men died

total provision  consumed in 5 days= 120 *5 = 600 man days

persons left after 5days = 120- 30 = 90 men

total provision left = 24000- 600 =23400 man days

No of days it can last for eremaining people = 23400/90 = 260 days

Thus, the remaining provision will last for 260 days
