Q.
In a mens hostel, there were 95 students. To accommodate 30 more students the average is decreased by rupees 5. But total expenditure increased by Rs.500. Find the total expenditure of the hostel now ?
A.
Rs. 4680
B.
Rs. 4420
C.
Rs. 4960
D.
Rs. 5480
View Answer
Correct choice: A
Explanation:
Let the expenditure on the 95 students be 'x' Then, 95x + 500 = 120(x – 5) 95x + 500 = 120x - 600 120x - 95x = 1100 25x = 1100 => x = 44 Therefore, total expenditure of the hostel becomes 95 x 44 + 500 = 4680.
