(m-n)(m+n) = 1954 = 2*977
(m-n) and (m+n) r same in the sense that
if m-n is ood then m+n is odd
if m-n is even then m+n is even
they cant be odd coz 1954 is even
and if both r even then (m-n)(m+n) should be a multiple of "4" but 1954 is not a multiple of "4"....hence no solution....

29 = 1XXX in roman
take "!",u will get XXX = 30....i think.....
next one :
X*0.05 + (2000- X)*0.04 = 92
====) 0.01X = 12 ====) X = 1200
