A hostel has enough food for 1860 students for 60 days. If after 20 days, 930 students leave the hostel, then how long will the food last now?
Answers
Answer:
So, the food will last for 36 more days instead of 45 days
Step-by-step explanation:
120 x 60 =7200 student days
120 x 15 = 1800 student days
Subtract =5400 student days
No of students =120+30=150
No of days = 5400/150 = 540/15 = 36 more days ANSWER
Answer:
The food last now for 80 days.
Step-by-step explanation:
Total number of students remained after 930 students left the hostel=1860 - 930=930
As after20 days 930 students leave the hostel
Food remained for =60 -20=40 days
For 1860 students, the hostel has enough food for 40 days
∴ For 1 student, the hostel has enough food for 1860×40 days
∴ For 930 students, the hostel has enough food for (1860×40)/930 days
=80 days
