Solution:ABC$ + #DEF& = ?GHI!2*@
A → first from the left end,
@→ first from the right end.
B→ second from the left end,
*→ second from the right end
C→ third from the left end,
!→ third from the right end
Similarly,
ABC$+#DEF&=?GHI!2*@
$ → fourth from the left end,
! → fourth from the right end
#→ sixth from the left end,
H→ sixth from the right end
E→ eighth from the left end,
?→ eighth from the right end.
!H? Is the correct answer.
