Bandwidth digital communications

The bandwidth efficiency of a digital modulation method is the ratio of transmission bit rate with respect to minimum bandwidth

Given that there are 12 different message signals and the bandwidth of each signal is given then how to find out the bandwidth required to multiplex these message signals

Given a binary communication system given the transmission data rate it is also given as r z signalling then how to find out the minimum bandwidth required for the above system
