Min-young, Min-ju, Min-gi, and Min-ji each drank milk, and realized there was a number written on the bottom of the milk carton. Min-young's number was 21, Min-ju's number was 9 less than Min-young's, and Min-gi's number was 17 more than Min-young's. When the sum of Min-young's and Min-ju's numbers minus Min-gi's number is equal to Min-ji's number minus 5, what is the number written on Min-ji's milk?
