  Hihi,

  The stress master is back! Here's another IQ question for you peeps!

  1. You have 2 identical mozzie coils.

  2. Each burn for 1 hr exactly.

  3. How to tell the 45th min from the time you ignite?

   

  Good luck!

  Actually u cant, unless u have a stopwatch,

  is like giving u a string and a lighter and ask u to time 45 minute for me.

  first cut the mozzie coil by half, then burn the half mozzie coil, from both end, so you can time 15 min, then burn the other coil ,you get 1 hour, minus the 15 min, you got 45

  or u just take out a stop watch and start the clock after u ignite and wait till it shows 45 min.

  coil A and coil B

  burn A one end, B both end.

  30 minutes later......

  B is burned up, A left with half.

  burn A at both end

  15 minutes later......

  A burned up
