Can some one explain to me about how to determine the number of bits to borrow lets say for a Class C address (211.212.10.0)?

It would be the first 24 bits.

255.255.255.0

Leaving the last 8 for hosts.
This can also be subnetted again.

First you will have to determine the require no. of host and subnet. For class c,borrowing 2 bits on the host portion will give you a subnet mask of 255.255.255.192,this will allow you to have 64-2=62 usable hosts. (2 is for network and broadcast).This would mean that if you are using 202.57.32.0 your first network will be 202.57.32.0-202.57.32.63,usable hosts is from 1-62.
