The number of students in a hostel increases from 5400 to 6075. By what percentage should the hostel reduce the per head consumption of food, so that the expenditure on food does not increase?
Answer & explanation
Correct answer: option 2
Initial Number of students = 5400
Increased Number of students = 6075
According to question ,
required percentage = \(\frac{6075 - 5400}{6075}\) × 100
= \(\frac{675}{6075}\) × 100
= 11\(\frac{1}{9}\)%
