Answer 1

Answer:

After 14 days,

the ration is sufficient for 150 students for ( 50 - 14 ) days. i.e 36 days

After 14 days, 30 more students join the hostel.

So number of students in the hostel = 150 + 30= 180.

Let the ration last for x days, when there are 180 students in the hostel.

Hence, it is a case of indirect variation.

Therefore, 150 × 36 = 180 × x

=> x = (150 × 36) / 180

=> x = 30

Therefore, the food will last for 30 days.
