B. 300 lines
C. 350 lines
D. None of these
Solution (By Examveda Team)
To understand it will break one hour in 12 segments of five minutes.1st 5 Minutes = Thinks
2nd 5 minutes = Write.
3rd 5 minutes = Rest.
4th 5 Minutes = Write. [Because he can write up to 10 minutes if he thinks for 5 minutes.]
5th 5 minutes = Think. [He has completed 10 minutes of writing so he has to think.]
6th 5 minutes = Rest.
7th 5 minutes = Write.
8th 5 minutes = Write.
9th 5 minutes = Rest.
10th 5 minutes = Think.
11th 5 minutes = Write.
12th 5 minutes = Rest. [He has completed his 10 minutes of working. 5 minutes thinking + 5 Minutes writing.)
So, in one hour he will write 250 lines of codes.
