Provisions for one student =250×35=8750
250 students used provisions for 5 days.
Total provisions used by 250 student in 5 days
=250×5=1250
Remaining provision =8750−1250=7500
After 5 days total number of student =250+25=275
Total provisions used by 275 student in 10 days275×10=2750
Now Remaining =7500−2750=4750
After 15 days no. of student =275−25=250
4750=250× no. of extra days
No. of extra days =

4750

250

=19 days
