152. A book is printed in such a manner that each page contains a
certain number of lines, and each line a certain number of letters.
If each page contains 3 lines more, and each line 4 letters more, the
number of letters in each page will be 224 more than before; but if
each page contains 2 lines less, and each line 3 letters less, the
number of letters in each page would be 145 less than before. Find
the number of lines in each page, and the number of letters in each
line.
