Could you give the explanation for the more mortal ones ;)
1for 127141.......d unit digit is 7....
for 141127.......d unit digit is 1....
for 127.141................d unit digit is 7
and for d last one it is ....................9 so d sum's unit digit is 4...
..wats wrong wid this???
11(127)141 ends with 7 as 141= 4(35) + 1 and 74n+1 ends with 7.
141127 ends with 1.
127.141 ends with 7 and
(127.141)127.141= (17907)17907 ends with 3 as 74n+3 ends with 3.
So sum ends with unit place of 7+1+7+3 which is 8.
P.S:
Cut the mortal immortal stuff, bhaiyyah. pls
