The answer is 12 instead of 9, because every time you add 0.5 to the k, your loop condition is altered, because k changes, so it takes twice as long to go through the loop. That's why the answer is 12...

So sorry Aleksei Radchenkov , if the value of k changes everytime you add up 0.5. Wasn't it suppose to be infinite loop then?? How does the loop get stop

Kapama, Joshua, Nope.. 'i' variable gets increased by 1 each iteration, while k gets increased by 0.5. So it will just take twice as long, but it won't be infinite...
