110 passengers,50 in the upper deck and 60 in the lower deck.

25 passengers have issues as 15 refuse to be in the upper deck while 10 others refuse to be in the lower deck
So those 15 will be put in lower deck and 10 will be in upper deck

So from the rest 85 passengers(110-25), we need to find 40 people to put into upper deck and the rest go to lower deck

So the ways are: C(85,40) = 85!/40!45! . Answer 2
