Small signal voltage gain by one small resistance connected to emitter
through a large by passed resistance and junction to base resistance
for negative feedback. If small R is 0.22K and Rc=10K. What should be
its value?

You need to find a book on transistor circuit design. A college-level text
should be okay. The math isn't complex, so you shouldn't have trouble
understanding it.

Hint: Since the "big" resistor is bypassed, you can model the small-signal
AC gain as if the big resistor weren't there at all. DC feedback is the sum
of both resistors, of course.

His question looks to have been copied from a poorly written
textbook.

He's probably asking for someone to do his homework.

Flip to the back of the book and see if there is a section
called "Answers to selected exercises"...

Thank you so much for your valuable hint sir. This is not a homework
copied from any textbook. This arise in my mind while making a home
made material and your hint helped me a lot. Thank you.
