Answer:
40 days
Step-by-step explanation:
There is rations in a hostel for 150 students for 60 days.
After 12 days, 30 more students join
∴ Now total students = 150 + 30 = 180
Remaining days = 60 – 12 = 48
150 students : 180 students :: 48 days : x
More students, less days
∴ By inverse variation
180: 150 :: 48 : x
x = 150×48/180 = 40 days
∴ Remaining ration will last for 40 days.
hope it helps :)
