TWO possible answer for this question..
GoOd LuCk!!
Qns:
You have 10 bags of coin.. each coin weight
1gm.. out of the 10 bags.. one is actually the
counterfeit coin.. each counterfiet coin is 0.1gm
heavier than the real one.. each bag have 100
coins in it..
You have a weighing machine.. but this weighing
machine can only be use once.. as the reading
will not be change once you put any object to
weigh it.. remember.. it only can weigh one time..
reading won't variate even if u try to take out or
add in more things..
How do you find out which bag of coin is the
counterfeit one??
