@ashish-deo-singh same set of dates means a student can go on multiple dates also na?
I think it should 32 the ans
The total no. Of possible sets such that each student goes at least once is 2^5 -1= 31
Now if another student is added he will surely have same set of dates as some other student ...
So ans will be 31+ 1=32
