Question

the hostel of a college having 320 students has a stock of food for 80 days. if 20 students leave the hostel after 20 days,for how many more days will the food last?

Answer 1

Answer:

64

Step-by-step explanation:

320 students for 80days

total food = 320*80 = 25600

20 students leave the hostel after 20 days

so food used for the first 20 days = 20*320 = 6400

remaining food = 25600-6400 = 19200

19200 is food is available for 300 students

so number of days the food will last = 19200/300=64
