You were given 10 balls, except one all having same weights you need to identify that ball having different weight by using balancing equipment for just 3 times only.

• keep 5 and 5 for first time
  then one will be weighted high then take that 5 balls ,keep 2 and 2 in each .if suppose balls are in equal weight .finally the ball we kept aside is having different weight.
