IIFT
Consider the revenue per passenger = P
=> Total revenue = 24*4P = 96P
Since the total cost is proportional to interest, it can be assumed as 120*K
Total cost*(1+Profit/100)=Revenue
=> 120K(1+15/100) = 96P ..........(1)
New Revenue = 20*5P = 120*(0.9)K*(1+Profit/100) ..........(2)
Dividing (2) by (1),
25/24 = (0.9/1.15)(1+Profit/100)
Profit/100 = (25*23)/(18*24) - 1 = 1.33-1
=> Profit = 33%, Option A is the answer.
