Solution:

8.

Explanation:
- The Wire of the extension cord-1 is broken.
- The extension cord-6 does not have a wire.
- One of the sockets of cord-2 is broken
- The cord-4 with just one socket is of no use.

Now,
- Cord-1 will connect to the main switch and one of the sockets will connect to Cord-2.
So two sockets can be used from cord-1.

- One of the sockets of cord-2 will connect to the cord-5 and one of them is useless.
So two sockets can be used from cord-2.

- Cord-5 can use all the sockets, i.e. 4

So,
Total In Use = 2 + 2 + 4 = 8.

The competition was held on 11 November 2013. The logic is simple. In America, the dates are mentioned as Month/Day/Year and in Britain, dates are written as Day/Month/Year. But on 11 November 2013, the date and month will be the same. And thus both will write in the same manner i.e. 11/11/2013. If it would have been any other date, the evaluators would have been able to identify it.
