Here the trick is "He takes a break for five minutes after every ten minutes".
So, if he thinks first five minutes and after that he begins writing then after 5 min, he must take a break.
Hence in first round:
--------------------------------
5 min --> thinking(T)[100 lines]
next 5 min --> writing(W)[first 50 lines]
next 5 min --> break (writing is interrupted by break)(B)
--------------------------------
In second round:
--------------------------------
5 min --> W (Another 50 lines)
5 min --> T [100 lines]
5 min --> B
---------------------------------
In third round:
---------------------------------
5 min --> W (first 50 lines)
5 min --> W (Next 50 lines)
5 min --> B
---------------------------------
In fourth round:
---------------------------------
5 min --> T [100 lines]
5 min --> W (first 50 lines)
5 min --> B
---------------------------------
Hence, in total 60 mins,
Thinking : 300 lines
Writing : 250 lines
