Answer:
42 days
Step-by-step explanation:
In a hostel, 105 students had food provisions for 40 days
Clearly, the remaining food is sufficient for 105 students for (40 – 8) days = 32 days.
But remaining students = (105 – 25) students = 80 students
Let the required number of days be 'x'
Number of students : 105 80
Number of days : 32 x
Clearly, less students would have food for more days
So, it is a case of inverse proportion
.: 105 × 32 = 80x
=> x = 105 × 32/80
=> x = 42 days
Ans : The food provisions will now last for 42 days.
