• A. 250 lines
• B. 300 lines
• C. 350 lines
• D. None of these

Answer 1

Answer: (A)

250 lines

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 type 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.
