Total Ration is 150×60 = 9000
In 12 days 150 students Consumed 150×12 = 1800 Ration
Now 30 students left so remaining student 150-30 = 120
and remained Ration is 9000-1800 = 7200
So 120 students consumes 7200 ration in days = 7200/120 = 60 Days
In 12 days 150 students Consumed 150×12 = 1800 Ration
Now 30 students left so remaining student 150-30 = 120
and remained Ration is 9000-1800 = 7200
So 120 students consumes 7200 ration in days = 7200/120 = 60 Days

Answer:
Answer is 40
Step-by-step explanation:
After 12 days,
150 student for (60-12) days = 48 days
So number of student in hostel = 150+30 = 180 .
Let the ration last for x days, when there are 180 student in the hostel.
= 150 × 48 × x = 150× 48 /180 = 40
Hence, the ration last for 40 days
