I found it extremely difficult and took more than 10 mins only to understand the ques
Not sure if this is correct but still here is what I got-
Contiki:
plane tkt discount = 210-150=60 savings for the group = 30*4=120
discount = half of savings so 1st row room will be taken
worldsprings:
plane tkt discount = 525-450=75 savings for the group = 25*4=100
discount > half of savings so 1st row room will be taken
sunfun:
plane tkt discount = 240-210=30 savings for the group = 25*4=100
discount < half of savings
so 1st row room wont be taken up
revenue lost = 100 -30 -115/4(reimbursement)= 41
** I am not sure whether reimbursement needs to be multiplied by 4(for 4 days)
so
ans is No No Yes
I definitely wont be able to do this on the day of the exam.
Please experts need your advice to tell us some strategy to tackle such problems
