School reading contest

North Tirana Primary school is having a reading contest among students. A total point is calculated for every student who fulfills the minimum requirements from 4 courses. There is also maximum point (m) that students can get.

Weekly, every student has to fulfill the minimum pages from the four defined courses. If a student fulfills the minimum condition from all four courses, then he gets 5, 5, 4, 4 points respectively for every extra page that he reads.

In the beginning, you will be given two integers: the number of students (n) and maximum points that a student can get (m) where 0 ≤ n ≤ 1000, 10 ≤ m ≤ 1000. In the second line you will be given the limits of 4 courses. Then, in each of the following n lines you will be given 4 numbers which are between 0 and 500.
