30% of 60 will be accommodated at XYZ = 18
70% of 60 will be accommodated at ABC = 42

55% of 60 prefer XYZ = 33
45% of 60 prefer ABC = 27

we were asked to find number of maximum possible people who were accommodated at hotels they dont prefer,

So for 18 XYZ accommodations , we can choose 18 ABC preferring people (so xyz is filled up) Here 18 were given to people who dont prefer XYZ
for 42 ABC accommodations, we can choose 33 ABC preferring people and rest to ABC. Here 33 were given to people who dont prefer ABC.

So total people who were accommodated at hotel they dont prefer = 18+33 = 51

I calculated it using percentage figures alone 85% * 65 / 100 = 51
Thanks for the idea.

30/100 * 60 = 18 will be at XYZ

and the 42 will be at ABC

So Max # of representatives NOT given accommodations at the hotel they prefer = Total # of Rep - MIN # of representatives given accommodations at the hotel they prefer

So, all the 55% of rep who want to stay at XYZ can be moved to hotel ABC

and out of the 45% who want to stay in ABC, only 15% will be there and the remaining ones (45-15 = 30%) in hotel XYZ.

So total 85% are not give hotels of their preferences

=> 85/100 * 60 = 5100/100 = 51
