number of ration =60×500
=30000
number of ration for 12 days =12×500
=6000
rations rest =30000-6000
=24000
then 300 students extra joined,so total students =500+300
=800
days for which the rest rations will satisfy the students =24000÷800
=30 day
Inverse variation
No of student 500 800
* *
Ration last for 48 x
500*48 = 800*x
Solve the balance and you will get the answer as 30 days
