Answer 1

remaining provisis survive for 30 days

Answer 2

The remaining provision survive for 19 days.

Step-by-step explanation:

Consider the provided information.

A hostel has provision for 250 students for 35 days.

For one student hostel has provision for: 250 × 35 = 8750

250 students provision for 5 days: 250 × 5 = 1250

Now the remaining provision is: 8750-1250=7500

After 5 days 25 students was admitted.

So the total number of students are: 250+25=275.

275 students provision for 10 days: 275 × 10 = 2750

Now. the remaining provision is: 7500-2750=4750

Again after 10 days, a batch of 25 students left the hostel.

After 15 days the number of students are: 275-25=250

Now the remaining provision survive for:

4750=250×Number of days

Number of days=19

Hence, the remaining provision survive for 19 days.
