Question

There are 100 students in a hostel. Food provision for them is for 20 days. How long will these provisions last, if 25 more students join the group?​

Answer 1

Answer:

16 days

Step-by-step explanation:

no of days=y

no of students: 100 125

no of days : 20 y

they are inversely proportional..

100×20=125y

100×20/125=y

4×20/5= y

4×4=y

16=y

y=16 days
