Quiz time! What is the Burn, Progress?

[Nayeem Ahmad]

Hi Agilists,

Here is a simple question. 

For a task, the initial estimate was 10 hours. After 5 hours of work, remaining hours reported = 7

Questions:
1. Burn =?
2. Progress % =?

Note:

I am really interested to know what is your way of calculation.

Thanks in advance.
