I have 7 Candles lit Riddle.

I have 7 candles lit, 2 blew out. How many candles do I have left?

The answer of this riddle is 7.

 There are 7 candles lit and if I blew out 2 of them , I still have 7 Candles 5 lit and 2 unlit.

But still there is catch, if those 5 candles are lit longer, they will melt and we will be left with 2 candles.

So, Depending on the time when we count the candles answer would be either 7 or 2.

Since, in the riddle it is not explicitly stated the time, answer is  7.
