Got a link for the test : 75 mins and 4 questions

1. Given 4 input in form of (x,y,z,n) return numbers in range [1,n] where n is included which are multiple of x or y but not z. For example (3,4,5,12) answer would be [3,4,6,8,9,12]
2. Given 2 list of numbers return numbers numbers not in list 1 but present in list 2. For example list1 = [1,2,3,4] and list2 = [0,1,2,3,4]; answer would be [0]
3. Given timestamp in form of [id, starttime , endtime] return employee who take less than k break between calls along with their no. of breaks.
   For example [1,0,2], [2, 0, 2] , [1,2,3], [2,3,4] and k= 1 the answer would be [1,0]
4. Famous award top k hotels

Do i have any chance if i got two questions right and missed 1 TC each in other two?
