Blockchain.info says it took 3 minutes, are you sure you are not stating the time it took to appear unconfirmed?.
while transaction charge that I paid was about 0.0002btc which is very less for 0.0098btc .
The amount of coin does not matter, only the size (in bits) of the transaction.
Your transaction is just about the smallest possible, one input, one output.
while the friend who receive has problem with his transaction of yesterday , his 0.22btc is unconfirmed , you can see at the same adress who receive the bitcoin fastly .
Can you post transaction ID?

what your thoughts about it friends .
You paid a reasonable fee, made a small transaction, and had some luck.
That is all there is to it.
these are the transactions I'd of total of about 0.22btc which are unconfirmed .
