<pre>
(1)  His income in the first half of the year 2002 was  1500*6 = 9000  dollars.


(2)  His income in the second half of the year 2002 was  9000*0.75 = 6750  dollars.


(3)  His total income in the year 2002 was  9000 + 6750 = 15750  dollars.


(4)  Let X be his total income in the year 2001.  Then  1.2X = 15750;  hence,  X = {{{15750/1.2}}} = 13125 dollars.

(5)  Now his average monthly income in the year 2001 was  {{{13125/12}}} = 1093.75 dollars.     <U>ANSWER</U>
