answer.. 

as promise.. here is the answer..

i) take out one coin from one bag..
take two from the other bag..
take three from the third..
so on and so for till the last bag..
which ten coins will be taken out
from this bag..
put the coins onto the weighing
machine.. if the decimal point shown
on the scale is 0.5.. the bag that took
5 coins out is the fake one.. got it??
(each fake coin is 0.1gm heavier..)

ii)as for the second likely answer..
it's about the same as the first..
but, instead of weighing all 10
bags of coins.. one bag is left aside..
weigh only 9 bags.. taking out the coins
in the same sequence.. till the last bag,
which is the 9th bag.. take out nine..
the results is similar to the first answer..
the only different is one bag is left out in
this method..
