There were 45 students in a hostel, if the numbers of students increased by 7, the expenses of the mess were increased by Rs. 39 per day while the average expenditure per head diminished by Re.1. What is the original expenditure of the mess?
[ "A)575", "B)585", "C)595", "D)625" ]
B
Explanation: Let the original expenditure be Rs.x Original average expenditure = X/45 New average expenditure = (x+39)/52 So (x/45) – ((x+39) / 52) = 1 so x = 585 so, original expenditure is Rs 585 Answer: B

B
Let number of mangoes be x, number of oranges be 12-x 0.80x +(20-x)0.60/20 = 0.69 solving for x, we get x = 9 --> Mangoes 9, Oranges 11 Now, number of oranges to be returned be y 0.80*9 + (11-y)*0.60/20-y = 0.72 solving for y, y = 5 Ans: B
