what is the purpose of connecting resistor of 47 k between base and ground...
Mohan, if you really knows nothing about the purpose of such a resistor, I propose to follow my suggestion:
Instead of trying to find a workable transistor amplifier based on a trial-and-error procedure you really should study some transistor basics, in particular what a suitable operating (bias) point is and how it can be realized.
I am afraid, otherwise your activities are a waste of time.
