Ivan had to solve some Mathematics questions during a 3-week school holidays. At the end of the first week, the ratio of the number of questions solved to the number of questions unsolved was 3 : 5. At the end of the second week, Ivan solved another 27 questions and the number of unsolved questions became 1/4 of the total number of questions. How many questions did Ivan need to solve on the third week to complete his assignment?
