EXAMPLE

7 % 6 A # 5 P Q\[\div \]R + U 4 @ ` \[\times \] 3 \[\to \] H J * 2 \[\pi \]

In the reverse order of the above sequence, how many such symbols are there each of which is either immediately preceded by a vowel or immediately followed by a letter but not both?

(a) Two                         (b) Three                        (c) Four                         (d) Five

Explanation (b):

The reverse order of the given sequence is

 \[\pi \]2 * J H \[\to \] 3 \[\times \] ` @ 4 U + R  \[\div \]  Q P 5 # A 6 % 7
