Let A be a person in need of information 
from another person B. Let us assume 
that the quantum of information immediately 
required is a and also that it is available with 
B. a depends on long-term information 
needs of A which may be designated as b. 
Thus, 
a cc b 
or 
a = kb ..................... (!) 
where k is a constant depending upon earlier 
information available with B, assuming 
that B possesses all the information A needs. 
Let c be the amount of information already 
possessed by A. Then, 
a oe c 
or 
a = le .................. (2) 
where l is a constant. The constant l may 
be defined as information gap of A. 
Substituting the value of a in equation (1), 
we get 
le= kb 
............ ·········(3) 
The extent to which B can fulfil A's need 
depends upon A's information rather than 
skill (Kaul, 1984).

Let d be the amount of technical infor-
mation available with B, and let e be his 
skill in transmitting this information. The 
skill of B in transmitting information ena-
bles him to apply it to the specific problem 
at hand and this prompts him to gather 
more information about it or its related 
aspects. 
Then d = me where m is a constant wich 
depends upon the extension worker B as he 
transmits the information to his cJient A. 
The relationship between a and d is given 
by the degree of rapport as defined earlier 
(Kaul, 1984), wherein it was defined as the 
number of contacts needed to be sought 
from the client by the extension worker, 
upto the point the former starts seeking the 
company of the latter. The greater the 
degree of rapport, the closer win be d to a. 
The information needs in different societies 
differ according to the stages of their deve-
lopment; for example, such needs among 
Norwegian :fisheries are far different from 
those in Bangladesh. Thus, in Norwegian 
fisheries, d approaches a at a faster rate 
than in Bangladesh .
